Delegating Domain Names


You may change DNS servers list (delegate domain) and launch DNS servers testing procedure in "Manage your account" → My domains".

Domain delegation means placement of DNS servers list with the domain technical records (zone file) to DNS servers enabling top level domains functioning. Delegation is a prerequisite for site and mail operation on the domain.

Delegation Periods, Suspending/Unsuspending

Within the whole domain registration period the Registrant may suspend delegation in "Manage your account" → My domains" (for gTLDs and ccTLDs the domain should be delegated with an empty DNS servers list).

Earlier suspended domain will be unsuspended subject to domains delegation periods.

Domains delegation periods are subject to the moment the modifications are made:

  • for .RU, .РФ and .SU domains - up to 2 hours;
  • for third-level domains - up to 1 hour;
  • delegation of gTLDs and ccTLDs takes several minutes.

Important! A delegation request for .RU and . TLDs will be processed, unless RU-CENTER verifies the ability to contact Registrant by a registry held phone number with SMS support.

DNS Servers Testing

During domain delegation the specified DNS servers may be checked for operation. If testing proves successful the domain will be delegated with the new DNS servers.

How to Complete DNS Servers List

  • specify at least two DNS servers;
  • if you specify DNS servers, containing the name of the IDN, the name of this IDN should be entered with "XN--" prefix, but not in national script;

Irregular Cases

For DNS servers, which name contains the domain name to be delegated (child DNS server) IP address should be specified; .PRO domain supports only IPv4; For .ORG domains delegation with child DNS servers different IP addresses need to be specified.
