We are often asked: “Why, after registering the domain is not available right away? Why do I need to wait a few hours? After all, you say that the domain name registration takes only a few minutes, so what then caused such a long wait? “Around the same issues arise in the process of transferring the domain to our hosting:” And I, what can we expect? Domain is already registered in the address NS-servers I’ve changed. What’s the matter? “The legitimacy, and today we will try to understand in detail and to answer them.

To do this, let’s see how the procedure for registering a domain from the very beginning.

How does the “domain” kitchen?
Domain ownership technically and legally regulate the organization – the administrators of domain zones. This, for example, ICANN (the zone .COM, .NET, .ORG, .BIZ, .INFO), IANA (zone .US, .TV, .WS), the Coordination Center for TLD (.RU zone and .SU,. Code), etc.

Directly involved in domain name registration domain name registrars, which administrators to delegate the right domain registration, and who have access to a database of all domains (registry, registry) to change it.

Each domain zone, as a rule, there are several registrars: for example, today in the domain zone .RU about 25 registrars have domain zones .COM, .NET, .ORG, etc. – Countless registrars. Registrars maintain a database of registered domains, provide access to this database via the Whois and support root DNS-servers with the corresponding NS-records domains.

What can be done to speed up the process?
As you might have noticed, the main problem causing long waits health domain, caching is incorrect or outdated information about the domain. Naturally, the question arises – can anything be done to reduce the time domain inoperable?

When registering a new domain does not make sense to talk about any special measures have been: it is important not just impatient and voluntarily to wait at least an hour after ordering domain registration, and wait for the domain will be delegated to a “natural” way.

But when you transfer the domain makes sense to take a number of measures that will really help really reduce downtime domain.

You can try to contact the administrator of NS-servers to which is delegated domain, and ask him to change the TTL value for the zone records to the minimum. It must be done no later than the time specified in the current zone TTL NS-domain servers.

Before changing the list of NS-servers for the domain do not be lazy and use the nslookup utility to make sure that in the new NS-servers already available area of your domain and it contains the correct records (A, MX, etc.).
Verify the correctness of the zone for your domain in the new NS-servers, you can make changes in the list of NS-servers to which is delegated domain.

Many registrars offer is automatically perform an action, which is usually called the “testing area domain.” Its essence boils down to action, like the previous tip, but we would recommend to abstain from it, because there are cases when due to network problems (network connectivity problems) is an automatic test fails, even when correctly configured zone. As long as you decide what’s the problem – you’re wasting your time.

NS-changing list of servers for your domain, please refrain from accessing it at least for a time not less than the current value of the TTL for the zone in its previous NS-servers. Remember that the response containing outdated information on your domain cached on the DNS server of your provider – is the main culprit of “unavailability” of your domain, and help with minimizing the negative impact of caching you can only administrator DNS-server of your ISP. If the transfer process you will need to perform actions with the site at the new place of accommodation, ask your new hosting prvaydera, if they have any official domain names to access the site (eg, technical aliases).
Solving the problem of local caching, unlike caching DNS-server provider, you can speed up, clearing the cache resolver force – the good, you can do it yourself. For example, a family of operating systems MS Windows resolver cache is cleared using the console command:

ipconfig / flushdns

Universal means of cleaning the local DNS cache is to restart the computer.

We hope you have found clarity in all matters relating to transactions with domains, and given us tips will help you minimize the downtime of your sites and mail.

Bonding domains – an association of several sites in one search engine index. Site mirrors are generally of resources that takes place redirect. In the process of splicing is a transfer of weight referring domain to the domain to which the user is redirected. In order to find out what domain skleyan, I use the browser plug-RDS bar, if the domain is glued together, then that’s how it is displayed:

When necessary bonding domain? Bonding sites is needed if you want to change the domain names and keep the audience visitors, reference weight and the position of the grant, as well as TIC and PR.

In addition, bonding is needed in the case when you need to leave to issue only one spelling domain – WWW or without WWW available in several mirror sites. Another bonding domains is required if you set a goal to combine these sites, while retaining their audience and performance of one of the sites. On the same site link domain names resonate with the core.

Terms gluing domains. There are two ways of gluing the domains, which are conveniently used together. For Yahoo and Google, we need to make gluing using 301 redirect th, while Yandex identifies the main mirror site through the directive “code”, registered in the file Robots.txt.

Therefore, if you need to glue your domain for all systems of search engines use two methods simultaneously.

Glue the two sites for Yandex is possible through a directive in host Robots.txt. This file is in the root directory of your site. And even if you believe that your site is one of a kind and that he alone, still use the directive host. This is important, because you still have two mirrors: the first with www, the second – without the www. Prescribe a robots.txt following:

Host: site.ru
You need to make a successful website promotion, and for this it is important that the weight of the links, users affix accumulated it on your website. No matter how domain names are located and how users will put the link with or without www.

Another effective way to redirect – redirect it using the status code “301”. Desired document finally moved to a different url. To use this redirect ht access our redirect 301. If the file is not found in the root directory of your site, you can create it using Notepad. In this case, note that ht access – this is not the extension of the file and its name.

How to check gluing domains? Check domain already glued in several ways. For example, you search Google for Ā«info: name of the site” or go to the web-master Yandex and see what the main mirror site search engine Yandex identified. Or, as I said at the very beginning of the article – with the help of various plug-ins to the browser.

An alternative way to test gluing domain – use the service site analysis. Google search produces it for about two weeks with preservation of all traffic, while Yandex, connects sites in search engines for much longer.

In the end I would like to congratulate the commentator of August, they became abisab! Congratulations, thank you for your comments! Write me on e-mail the number of your wallet wm to I could list a small prize!
