I have installed Webmin on 3 CentOS machines and setup BIND on all of them, working fine. The names are e.g. ns1.myhosting.net, ns2.myhosting.net, ns3.myhosting.net. I have purchased all the domains from NameCheap. I want to Namecheap control panel > Nameserver Registration and added all three nameservers with their IPs.
The DNS of my domain myhosting.net is hosted with ClouDNS.net. I went there and created three A Records one of each nameserver.
Then I purchased another domain for my client clientdomain.com and set its nameservers to mine (ns1.myhosting.net, ns2.myhosting.net, ns3.myhosting.net).
I created DNS zones on my BIND server. Everything works great except when I check clientdomain.com on intodns.com it says following:
The parent nameserver d0.info.afilias-nst.org is not sending out GLUE for every nameservers listed, meaning he is sending out your nameservers host names without sending the A records of those nameservers. It's ok but you have to know that this will require an extra A lookup that can delay a little the connections to your site. This happens a lot if you have nameservers on different TLD (domain.com for example with nameserver ns.domain.org.)
What I understand from the above message is I need to create A record for each of three nameservers (ns1.myhosting.net, ns2.myhosting.net, ns3.myhosting.net) in ClouDNS..net which I have already done and have confirmed that by pinging and running dig command.
I will be really thankful if someone can help me to fix this.
