I seem to be in an odd position where I have only 1 nameserver and I cannot remove it.
what happened was as follows:
a few days ago my host changed my server ips and I need to do the set up myself. I attempted to follow the tutorial given to me by my host but it didn't seem to work (I found out why later), so with 3 ip addresses appearing in my panel I thought I had to move everything from the old ip to the new ip so thats what I did, I thought I needed to wait for it to propagate so I left it. and today I logged on and nothing had happened, so I went to try the ip change again and realised that I hadn't actually done the ip swap (the command has a # infront of it, presumably to stop noobs from changing their ip from 1.2.3.4 to 5.6.7.

. and now the old ip and everything I had put onto the new ip seems to have vanished, (AFAIK all of the files are OK) and I have one nameserver and my panel (directadmin) won't let me delete it so I can try to get it working again.
what I am asking is, is there a way to fix this or do I need to reinstall everything?
edit: its a VPS running CentOS
