Hi there, I use debian on multi-server setup, with ISPConfig 3 and 5 servers, web.mydomain.com (www server), db.mydomain.com (database server), mail.mydomain.com (mail server), nameserver1.mydomain.com (primary name server) and nameserver2.mydomain.com (secondary nameserver). Everything was working fine until I had to replace my primary nameserver, now I can only ping / ssh into web.mydomain.com and mail.mydomain.com, when I try to ping the other servers I get : This is the response I get from pinging db, nameserver1 and nameserver2. The IP address (126.96.36.199) is also the same for all 3 servers, rather than the IP address that should be there, i.e 188.8.131.52 for db.mydomain.com, 184.108.40.206 for nameserver1.mydomain.com and 220.127.116.11 for nameserver2.mydomain.com. I can also dig web.mydomain.com, nameserver1.mydomain.com, nameserver2.mydomanin.com, mail.mydomain.com but not db.mydomain.com. How do I change 18.104.22.168 to the correct IP's. Any help would be greatly appreciated, Thank you!
