Dear Boris Sleptsov,
Unfortunately your request to update name servers on photoartlight.com has been declined by the respective registry operator.
There are various reasons why this may occur, however this type of problem usually happens when:
1. The name server names that are provided are incorrect or
2. The name servers provided have not been set up with the zone of your domain name or
3. The DNS provided by your hosting provider has not been set up to DNS appropriate DNS standards

To correct your configuration, please follow this check list:
1. Please ensure that a minimum of 2 name servers have been provided. If your hosting provided is using 3 or more name servers, please provide the details for all name servers.

2. The name servers IP addresses must be static, and the name server host names must resolve to these IP addresses.

3. The provided name servers must be authoritative for the domain name. This means that your domain name zone record of photoartlight.com must exist on all name servers.

4. Name servers submitted much match the ones indicated in the zone file of your domain name.

5. The DNS servers hosting the zone should not give the following responses:
i) not responding or server failure
ii) not reachable
iii) non-existent domain (NX)
iv) host not found
v) permit ICMP requests (allow pings) – this requirement only applies to a select few ccTLD providers

Many registry operators will not permit the delegation of your domain name unless all name servers are responding correctly.

6. The primary (Master) name server must be the same as indicated in the Start of Authority (SOA) as shown in the zone record for your domain name. Only a few ccTLD operators enforce this DNS standard, so this problem is quite common.

7. At least one MX or A record must exist in the zone file for your domain name. Some registry operators will not approve the name server change unless both an A record and a MX record exists in the zone file of your domain name.

8. The domain name of the name server host name provided in the SOA cannot be a CNAME. This type of scenario is a non-standard DNS configuration, and it is not a common problem.

9. Where a MX record is listed, it must not have a matching CNAME. This type of scenario is a non-standard DNS configuration, and is not a common problem.

10. The zone serial number for photoartlight.com must be the same on all name servers. Only some ccTLD providers perform this check, however to ensure correct operation of your domain name, it is highly recommended that the zone details are the same across all name servers.

Please make these appropriate checks and corrections, and re-submit your name server update.

Alternatively, you may use our free DNS forwarding service to point traffic to your web (www) and mail (mx) servers. This action can also be initiated by logging into our web site.

If you do not understand any of this, please contact your web/email hosting provider and ask them to follow up with these changes.
