I have a win2008 server which running IIS and say the server IP(i.e was registered with myname.com, and I also have other CNAMES like myname1.com and myname2.com registered for the same IP. Now I need to re-register myname.com to another IP. is there anyway that I can still keep myname1.com and myname2.com continuing served by the IP 721.5.5.5?

Please provide detailed instructions.

CNAME records point to a dns name, if you want to have those names point to the old IP then create new A records pointing them there and delete the old cname record pointing them to myname.com.

Here is some info no how cnames work:

I think I missed something... the myname.com will be set up on another server and register with a new IP address...
Please let me know if the following steps will work in my case.

1. delete the records for myname.com to the old IP ( and make default site as  myname1.com  
2. create a new records for myname1.com  to the old IP and keep myname2.com  there
3. register myname.com with the new IP

Ok I think I know what you want to do:

Keep the current site up until the new new server is up and running ?

If so then simple:
Step 1 create a new A record for
myname1.com pointing to
Step 2 create a CNAME for myname.com pointing to myname1.com
Step 3 create a CNAME for myname2.com pointing to myname1.com
Step 4 Delete the CNAME for myname.com
Step 5 create a new A record for myname.com pointing to the new IP
Step 6 (If needed) change the CNAME for myname1.com & myname2.com to point to the new site myname.com

step 6 won't be necessary since myname1.com & myname2.com will stay on the old server(
my old server has server name myname. Do I need to change it to myname1during the changes?

Without a better idea of what your environment is like, this is hard to answer.

However if this is just  website, there should no need to change the server name.
