I am trying to clarify my Reverse DNS PTR lookup for a domain. I have a server with a single IP addresses and multiple accounts, all sharing that IP address;
My PTR is currently:
24.210.31.in-addr.arpa. 14400 IN PTR domainname.co.uk.
But the domain that the IP address reverses to is
ns1.domainnetwork.co.uk, therefore should the PTR record on the account reference the primary returned domain rather than the account domain?
I can't seem to find any clear guidance on this with Google searching, however this question did seem to suggest that the account should reference the server domain rather than the account specific domain.
So, would having :
24.210.31.in-addr.arpa. 14400 IN PTR ns1.domainnetwork.co.uk.
in the DNS for the account give it a valid PTR record, even though this doesn't mention the account domain at all?
Edit: To clarify, the
ns1.domainnetwork.co.uk is the primary name server for the domain.
UPDATE + EDIT
I have a persistent issue with this topic, and felt it best to resurrect this incompleted query than to start a new one from scratch.
All the above still holds true.
I have a server with various domains, on an IP address .xx.xx.xx.236 and
xx.xx.xx.238 . I also have a single domain on its own IP address just for that doman (for the TLS certificate), which is xx.xx.xx.241 but I can't get that domain to correctly show a vaid
PTR record in the DNS.
A domain on the server that works (ip address 22.214.171.124 ):
websitename.co.uk 14400 IN A 126.96.36.199 55.34.12.in-addr.arpa. 14400 IN PTR nameserver1.network.co.uk.
the above works and gives a valid PTR feedback.
nameserver1.network.co.uk. is the same primary name server as the domain which sits on its own IP address (188.8.131.52) but which never gives a correct PTR record.
The domain that does not give out a valid
PTR record (unique IP address):
websitenameTwo.co.uk 14400 IN A 184.108.40.206 55.34.12.in-addr.arpa. 14400 IN PTR nameserver1.network.co.uk.
What Am I missing to make this record have a valid PTR DNS record?
