Registrators of domain names

April 29th, 2008 by Samuel Becks

Let us consider the scheme of “possession” of domains in order.

Registrators of domain namesChief coordinator of the Internet, distribution and administration involved in IP-addresses, domains and backward domains, is a nonprofit organization IANA (Internet Assigned Numbers Authority, the Agency to provide the names and unique parameters protocols Internet). The structure of Internet governance - hierarchical, therefore, not difficult to guess that a tree at the second level are the regional coordinators. These coordinators to date recorded four, and they called Regional Internet Registries (RIR). Among them are ours, the European Organization RIPE NCC (Reseaux IP Europeens Network Coordination Centre, the European Network Coordinating Center). In fact, it not only European, because it deals with the distribution of IP-addresses and domains in the territory that includes Europe, Middle East, Central Asia and African countries in the northern hemisphere. A total of jurisdiction RIPE NCC is coordinating domains and IP-addresses one hundred and nine States. If you are interested in learning more about the regional distribution and the history of these organizations, visit a special section on the site RIPE NCC. At the same site you can see, as coordinator belongs to one country or another.

It is not difficult to see that domain registration services in Beijing offers many more organizations. Among them - secondary recorders, hosting, Internet Service Providers. All of them use the services of one of the official registrars. It is no secret, and not bad as someone may seem. What we generally received when the market has reached a large number of registrars? We should note that most of them offer registration of domain registrars on prices, and many and below. But most importantly, the emergence of many registrars, we have received high-quality service. Now we can not sit on a complex multi-application for registration of domain and poschelkat keys in the web interface and, after registering a domain name and still manage to get a convenient interface. Also, many registrars free prescribe your domain in their name-servers.

Who is to choose among a large diversity of registrators? There are a few tips. If you already have a quality hosting, which you’re happy and who are not going to change, it is logical it would be to shift the care of registration, domain support and linking it with your site for hosting. The more so that most hoster provide such services.

The second option - if you have a leased line from a good provider, you have your own Web server, but you are not satisfied with third-level domain, normally provided by the Internet provider. Then logically would like to register your domain provider. He will make the necessary settings, and pay for a domain name through the Internet service provider you might need, that is as you usually pay for Internet access.

And the last option (it can also be the first:) - apply directly to primary or secondary registrar of domain names. Many firms that specialize in providing specific services like “interception domains”, will also help choose a name for your domain. - In general, all options are good - choose to taste. The main thing is that you are satisfied with the proposed level of services. And if many features, you can always choose the best registrar. At least, from your point of view.

Domain Names: Introduction

April 22nd, 2008 by Samuel Becks

In short, the domain name is a “facade” - call (sequence of words), which enters users in the address bar browsers to visit your site, but which is not a valid address of your site on the Web. Domain names are linked to servers Domain Name Assignment System (DNS), which are used to translate digital addresses (known as IP addresses, or Internet Protocol addresses) in the word. Every site you visit on the Net, except his name is still and digital IP address, which is addressed by this site on the Internet.

Domain Names, .com, .net, .org

Total (generic) Top-Level Domains

Typically, domain names are classified according to their extensions, which represent a domain name identification codes. The three most popular types of Higher Level Domains (TLDs) - This domains, which are not tied to any country:

. COM: Short from. commercial, which means “commercial”. Domain names with the extension. Com on its popularity far exceeds other names and can be purchased by any person or company.

. NET: Short from. network, which translates as “network”. Originally, this domain was created to expand technical websites. But with the expansion of domains can be registered at will.

. ORG: Short from. organization, which means “organization”. Initially, it is intended for non-profit organizations and other organizations that do not use expansion. Com or. Net. Currently, a domain name with the extension. Org can be filed by any person or company.
Domains countries

Domain names can be assigned to the use of country-specific extensions
. Each country has its own domain extension; Canada, for example, uses the extension. Ca, Japan -. Jp and Russia -. Ru. In most countries there are special rules, which describe exactly who can register domain names using this extension, and for what purpose, it is therefore important to examine the object before anything done.
Alternative domain names

ICANN, the organization responsible for the administration of top-level domains across the globe, has recently approved several new extensions, which are not assigned any specific country. Among them:

. aero
. biz
. coop
. info
. mobi
. museum
. name
. pro

Each extension has been created for use for certain purposes and is accompanied by certain restrictions. More detailed information on these top-level domains, you can find at: http://www.icann.org/tlds/
Other domains expand

In searching for a suitable domain name, you can find sites that claim to use such as the expansion. Xxx,. Free and. Mp3. This is not a real expansion and they are approved by ICANN, rather, their availability is guaranteed for the user software. Because ICANN is not approved is not one of these extensions and, in addition, users who do not have the appropriate software, can not gain access to sites with names, the data expansion should only be used for some secondary goals.

While expansion. Com,. Net and. Org usually all on hearsay and the mind are not the only expansion that are available for use. From a functional point of view domains countries work as well as any top-level domain, and the expansion of alternative work not worse. Therefore, do not use the top-level domain mediocrity when you can find better with another extension.

Common Problems of Virtual Hosting

April 19th, 2008 by Samuel Becks

1. Overcrowded servers

This is one of the most common problems of web hosting industry (in that it concerns a virtual hosting). Although it is not innately problem virtual hosting. This problem is usually associated with poor management of server resources, poor business planning and reactive rather than anticipatory behavior hosting company.

This is one of the first problems to which should pay attention to when choosing a host. If the buyer (and I think it is you) chooses before deciding to buy, and in doing so knows that go, and, just as importantly, knows what to guard against, all should be in order.

2. Security issues

4 In an ideal world, all you need to be done by web hosting companies - a server to connect to the Internet and to ensure that the server worked without problems. But the Internet can not be described as peaceful place. There is a wide variety of “internet terrorists.” Sometimes they are called hackers. No matter how you call them. It is important that they make the life of every decent hosting business harder than it should have been.

However, hackers and crackers - is extreme case. The network ordinary people are not like in real life. When hundreds of people had access to a computer (the server), it is likely that one of them will not entirely honest.

In addition, a virtual hosting environment can often find that you can easily get access to the accounts of other persons (collectively account when hosting - it is actually a directory (folder) on the hard disk server). Fortunately, the situation is not alarming, because, in most cases, what you save on the server, in any case, is for the public.

But there are a lot of things you have to keep secret. For example, if you sell software, you will not be able to afford such “leaks”. If you have a newsletter and you have saved email addresses of its subscribers to the server, you will likely not want to fall into the wrong hands. There are many examples, and that a few of the obvious examples.

In most cases, the security server, which hosted many websites, worse than that of a dedicated server. Usually, as in real life, there is a compromise between security and freedom.

3. Problems related to the Neighborhood.

What I call the “neighborhood problems” - a complex problem, but they all have one feature: they all relate to the fact that other people are doing on the server. These people (and their Web sites) are very close to your neighbours online and are also important as your neighbours in real life.

If one of those neighbors using an account in order to test a new script (and he is not the master of his case), then you (and all others on that server), there is a risk that one day one of those poorly written scripts may withdraw server failure.

One of your “neighbors” can belong to a curious type. Sometimes, it sometimes happens that the person has the necessary knowledge to access files in your account. As if someone completely searched your house. And although the cause can serve as a mere curiosity, unless it can be a serious excuse?

Also, there is another related to the Neighborhood thing, but for the most part, it concerns the Internet’s inner workings, but not people. This is connected with the work of search engines and Web hosts. In hosting environments used collectively IP addresses are allocated dynamically. Furthermore, the server where your hosted Web site can be hosted sites for adults and from time to time they may be attributable to the same IP address as you.

If the search engine will determine (erroneously) that the IP address associated with the site “for adults”, then your website can be considered relevant to the subject and eliminate adult filter “search engine, which can lead to a reduction in the number of visitors to your web site.

The easiest solution would be to ask your own IP address. Unfortunately, some hosts do not provide this service. Others are asked to pay extra each IP address, which usually is about $ 2 a month. Still, there are hosts that from the start will give you an IP address, although this does not mean that they do it for free. The price may be a little higher, as such a right is given to you “by default”.

The best hosted on those servers that do not have web sites for adults. Some hosts using the following technique: they host web sites for adults on some servers and websites general use - in the other. Also some hosts do not provide hosting services web sites for adults, while others host very similar websites. The

Web Hosting Resellers

April 17th, 2008 by Samuel Becks

Web hosting resellers

For some, this dream about your business, others - people who disappeared with their money for hosting, reseller for third - is the person who provided the stable operation of the site, helped to configure and customize the system and not for a very high fee is hosting, sometimes non-standard configuration, which is obtained from large companies difficult.

Considering as client.

Reseller business is simple and complex at the same time. It does not require a major investment, or even a schoolboy with $ 10-20, resellers can open an account by the owner or the largest server hosting company and the next day (if you are lucky) 2-3 clients accounts to sell their classmates. A week later - a few more, and have already returned their money, and effort in and earn a few bucks.

With the advent of a greater number of clients has become solidly profitable, in a couple of months is the time when the papers still need disk space at the “higher level” - which is also often a reseller, only larger. Business is growing and growing, BUT …

The above picture is not always so fine and easy because:

Schoolboy (among them many beginners resellers), is not always have the minimum of knowledge to provide at least some support for their customers, and if there is a more complex issues at the user’s response have to wait for days until the gore-reseller clarify somewhere reply and answer you. If the answer …
In the case of such an organization is difficult to expect that people from the computer is rooted, and that the decision raised questions you have - № 1 priority from your reseller. The degree of responsibility - relevant. And just now, you may tire reseller …

Another problem. The money collected. On the same day spent on film (wine, cigarettes) - no matter where. A 3-5 days to pay the owner nothing server and the Pope did not give more money. Result - disabling 10-20 reseller account and client accounts with him … Could rasproschatsya with their money, and that it is often more serious and sad - all data bases and their account. If this is a simple html - site - restore it’s not a problem. And if the dynamic? Forum or portal? And you are not doing backup 2-3 weeks? Even if you figure out a server that was your site (that is not a fact) - base with him you have given, because you are not data-center owner and not the customer.

So, despite benefiting from the usual cheap these accounts, the problem often outweigh the benefits.

Unix or Windows? Choice of the Hosting Platform

April 15th, 2008 by Samuel Becks

Windows Or Unix (FreeBsd) hosting

This question, the answer to that is obvious to an experienced webmaster might be put to a standstill newcomer.

Below, a comparison of the two most popular platforms - UNIX, and Windows supported by the overwhelming majority of providers. Just an attempt to dispel some misconceptions regarding these platforms.

One of the biggest misconceptions among newcomers - that you have to run the site on the platform, which was used in the design, ie, if it is placed on the project under the UNIX server, then it needs to be developed on the machine under UNIX. This is not the case. The operating system on which you are working on your computer, creating a site that can be anybody.

Accessibility hosting platform

In recent years, providers have made every effort to facilitate the administration of clients and sites under UNIX and Windows machines. Today there is no difference between these platforms relative to the simplicity and ease of use. If you - and the advanced user to use shell, select UNIX. However, if you are a newcomer, you will find on both platforms user friendly control panel with a web interface.

Hosting Reliability

Specialists agree that UNIX is more reliable. However, my personal experience 3 - IIS 3.0 years of operation under Windows NT 4.0, shows that the reliability of Windows platform can be significantly closer to UNIX. In far more impact on the reliability of the proficiency of staff. This means that you can decide on the choice of platform, given the differences in the first features of other platforms.

Performance Hosting

There is not any significant difference between the two platforms on the performance on tasks hosting.

Functionality hosting

This factor, the platform on which the two differ most. But there are not many tasks implemented on a single platform, and which can not be sold to another. The main difference is how to achieve this result. For example, if your site uses a database, you can use a link PHP / MySQL under UNIX or ASP / MS SQL for Windows. The trend develop solutions that will be supported on both platforms. For example, Microsoft FrontPage, and supported UNIX and Windows.

The cost of hosting

Here UNIX has an advantage due to the fact that, firstly, the majority of UNIX software products distributed under a license free of charge, and secondly, to UNIX is much easier to achieve the same level of reliability and performance than Windows.

If you definitely do not plan to use technologies and solutions, supported only Windows platform (see below), it likely makes sense to choose the UNIX platform.
