RDNS PTR Plesk Web Server
Posted on 2008-10-15
Plesk 8.6 / CentOS
I have a client that hosts their website on my Plesk server.
They have an in-house Exchange server which sends mail directly via DNS.
They have ATT for ISP.
I asked ATT to setup RDNS for their inhouse servername -> Local Office IP.
ATT wont setup RDNS but will transfer the DNS zone.
So I had them transfer it to my webserver nameserver.
I setup a PTR record under the clients domain account. IPADDRESS > office.domain.com
When I run a report at dnsstuff it shows that ATT has given my server authority but when queried it doesn't reply with a PTR record.
I just moved this webserver so it got new IPs but that was a couple weeks ago and i highly doubt its DNS lag.
This did work prior to upgrading the webserver.
188.8.131.52 / 8 PTR office.arcoa.com.
is how its set in Plesk
