- The maximum number of name servers for a domain is 11.
- An active domain must have at least two (2) name servers.
- It is possible to register a domain without specifying any name servers. In that case the domain will only exist in the registry database and not be propagated into DNS.
- Adding an IP address is mandatory only if the name of the name server is located under the same domain (is a subdomain of the same domain). E.g. ns.name.ee if the domain is name.ee. In such a case, the IP address recorded in the registry will be added as a glue record to the zone file in the .ee root name server. In other cases, adding an IP to the name server is not mandatory or reasonable, as it will not be used.
- One name server can have more than one IP address. IPv4 and IPv6 are both allowed. In case of a glue record, at least one IPv4 address is required.
What should be done if there is a need to change the name servers of a domain?In case of a change in the name of a name server, the corresponding change must be carried out in cooperation between the registrar and the domain's registrant or a representative of the registrant. If the IP address of a name server changes, it can be changed in the registry only by the registrar administrating the domain under which the name server is located. If the IP address of the name server has not been entered into the registry, there is no need to do anything.
If the domain was out of the zone, because of expiry or some other restriction, how long will it take for the domain to get back to DNS after the status has been lifted?Zone file renewals take place every 10 minutes. The propagation of the change on the Internet may take longer, depending on the configuration of the solving name servers servicing the local network.
