How does the domain transfer work? Part 2

From describes the following two conclusions:

When will take longer than the time zone TTL from the old NS-domain servers, DNS-server ISP address the root servers top-level domain, find the address of the new NS-servers for a domain, refer to the new NS-servers and updates the information about the migrated domain.

Dissemination of information about changes in the Internet domain (also called “domain zone update”) – this is an asynchronous and uncontrolled process: its speed depends on the settings of the previous NS-domain servers and DNS-servers status of each particular ISP. Accordingly, this process can not be controlled, and it is impossible to accurately predict the time of its completion.

Thus, instead of resentment and accusations of a new hosting provider to which you are transferring your domain, it is wise to be patient after the change of the list of NS-domain servers, but better – follow the recommendations listed below to reduce idle time of your domain.

For clarity, the process of redelegation domain can be compared to the procedure already mentioned replacement passport.

That’s no longer a young man comes to the passport office (panel registriratora) and apply for a replacement passport (for redelegation domain). Then he waits a while until checked his data. If everything is correct, he is given a new passport, and data on the new passport “spread” in the various registries government organizations. Of course, it takes some amount of time and, in contrast to the previous example, is often accompanied by all sorts of organizational overlays: somewhere information can not change where things will change, but very nebystro, etc.

As a result, the owner of a new passport, arriving at the bank for a loan, even a month after the change of passports, runs the risk of failure, since the information about his new passport at the branch may be missing. And the man did have to wait for “cache refresh” – retry after information about his new passport will get to the bank in the prescribed manner.

How does the domain transfer work?

Transfer Domain (properly called this process a re: not to be confused with the process transfer a domain from one registrar to another) begins with an application to change the list of NS-servers. Typically, the application is submitted to the Registrar’s website (in Control Panel) by specifying the new NS-addresses of servers that need to produce redelegation domain.

When making changes to the registry depends on the settings of the registrar and is usually less than 30 minutes.

But then begins a procedure that usually causes the most confusion and even negative, and can take up to several days: on the DNS-servers, Internet service providers, through which access to the portability domain, not the actual cached more information about the values of the old records of his zone.

To understand why this depends on the inertia of the DNS servers of Internet providers, make a small technical digression and consider the domain information stored on NS-servers to which it has delegated.

The domain information stored on NS-servers, and has a unified structure comprising standard parameters regardless of the type of domain. We are interested in a parameter called TTL (Time to live, time to live). This parameter specifies the time the relevance of data caching queries (in seconds). It is in this setting guided DNS-servers of Internet providers, when they decide – to give in response to a request old information or go to NS-domain server and request a new one.

The value of the lifetime depends entirely on the will of the administrator NS-server domain. Selecting it, the administrator is guided by different considerations, and the most common of these considerations – how to minimize the number of calls to its NS-servers. It is clear that the larger the TTL value will expose the administrator, the less DNS-servers, Internet service providers will look to its NS-servers by caching the previously obtained data about the domain and giving them to end users.

During this time domain transfer plays a strictly negative role: all clients ISP, DNS-server is cached information about the portable domain, will receive outdated information over time, not less than that indicated in the TTL domain zone carried on the old NS -server. For example, if the TTL is equal to 86400, updating data on the portable domain will be delayed at least a day.

Some of the most expensive domains of all time

Sold in 2006 for $ 1,500,000

The purchase and sale of the domain between the two Norwegian companies is dated 2006, but was made public only in 2007, when he published financial statements. And Tandberg Tandberg – both from Norway – finally agreed who gets the name.

Tandberg Data – manufacturer and supplier of solutions for backup and archiving, has decided to accept an offer to purchase a domain from provider of visual communication products and services Tandberg with headquarters in New York and Norvegii.Vprochem today Tandberg (the one that bought rather than one that is sold) is included in Cisco, and domain, the price of which $ 1.5 million is only used to redirect visitors to the main site of the company

Sold in 2009 for $ 1,525,000

Domain was sold to a company profitable, which trades names. But what happened to, and as things stand today, it is not known – the server does not find him, and in the range no name.

Sold in 2008 for $ 1,659,000

Company Minnesota’s Associated Computers, Inc., finally gave up and sold the company ESS Data Recovery, has long tried unsuccessfully to buy it.

To this day, the domain functions to the official website of the company, which has not stinted and yet redeemed himself coveted name.

Sold in 2009 for $ 1,700,000

It was rumored that not even sell for $ 1.7, and $ 2.5 million. But according to official statements, the domain is still sold cheaper company Real Estate Disposition Corporation’s (REDC).

“For years I wanted to buy this domain, and am very pleased that we were able to buy a top-class name – said the deal CEO Robert Friedman. – REDC without question the number one in the US and in many ways the global real estate markets. And this domain should belong to us from the beginning. Finally, we bought
