Changing Nameservers IP's - Help needed (especially for .com.au)
I currently have a server. It is running it's own nameserver IP's on the same machine (ns1.old.com and ns2.old.com). I am planning on moving all the domain on this server to a new server. I will keep the same nameserver names, but obviously the IP's will change.
From what I understand, the process is pretty simple for the most part for .com type domains. My problem is with .com.au domains. When we delegate a .com.au domain we need to specify both the nameserver names as well as the IP's of that server. This means when we go to move the server we need to redelegate all the .com.au domains (what a hassle).
What I need to know is;
a) has anyone had any experience with this for .com.au domains?
b) how did you approach it to reduce downtime for your .com.au clients?
c) is there a way I can avoid a similar problem in the future?
With question c), what I was thinking was getting my own IP's and running the nameserver info seperate to the domains. At the moment the IP's are obviously owned by whichever hosting company I lease the server through. Is there a way I can get my own IP's so I never have to go through this nightmare again, even if I decide to move the clients from one server to another?
Any help/comments appreciated.
