How does the domain registration work?

Domain Registration begins with the order for the organization’s website, providing such services (registrar) – fill out the form in which the data indicated the future owner of the domain. Ordering can be done in different ways – from manual to auto fill forms software interaction.

Registrar verifies the correctness of the application and, if all is true, produces domain delegation – shall record the new domain to the registry. In particular, this record contains information about the NS-servers, which will be located domain zone.

Time after which it becomes available on the Internet a new domain, is the sum of periods of time, which consistently ranks each stage of registration:

Order processing time for the registration of a domain, that is – from the point of application for registration by the user prior to becoming a domain registration. This time depends on the settings of the organization through which registered the domain required for the formation of the order time is usually counted in minutes.

Actually domain registration. Registrar verifies the correctness of the application, for some domain zones (for example, .SU, .RU, .RF) domain status changes to “Registered, is not delegatedĀ» (REGISTERED, NOT DELEGATED). That is, the domain can not be registered on the data of another person. This procedure is usually also takes time counted in minutes.

Domain delegation. Registrar shall enter in the register entry NS-servers, which will be delegated domain, and the domain changes the status to “Registered, delegatedĀ» (REGISTERED, DELEGATED). After some time entry from the registry is updated on the root servers responsible for the top-level domain zone. So, some time in the domain information in the public Whois base may appear that it is registered, but is not delegated. The duration of this procedure depends on the settings of a domain registrar and generally up to 30 minutes.

If the domain has been accessed prior to its registration, a negative response is cached on the DNS-server ISP through which the treatment. Until an update on these cache DNS-servers, when applying to a domain will be given information about the non-existent domain, although the rest of the places where “premature” had no complaints, the domain will be available. In this case, we can only wait, when to update the information in the cache DNS-server ISP.

The update time depends on the settings DNS-server of your Internet service provider and can be tens of hours.
The operating system of any computer connected to the Internet, there is a component called “resolverĀ» (resolver), responsible for domain name resolution resources that are accessed from applications. For example, when you type in the browser the domain name of the site, your browser asks for information about the domain resolver to the operating system, and the resolver – the DNS server your ISP.

Data on the negative response when accessing domain and get a DNS cache resolver operating system, and go from there only after some time. The value of this time can not be ignored, because you as the owner of the computer can affect it (more on that later).

For clarity, the registration of a domain can be compared to the procedure for obtaining a passport.

Then he waits a while until checked his data. If everything is correct, the passport goes on clearance. After the procedure of registration data about the passport shall be made in the various registries government organizations. Prescribes that it is such a passport belongs to a given individual. Of course, it takes a certain amount of time. After all this man comes at his passport and takes it into use.

Updating DNS cache can be compared with the situation when a person applies for a passport, the same day goes to the bank for a loan, and is denied because of information on his passport at the branch is not available. The person will have to wait “cache refresh” – retry after his passport information fall into the Bank in the prescribed manner.
