[isp-dns] Moving DNS servers to new domain

["Jim McAtee" <jmcatee@...]

Two questions:

I'm considering moving our two name servers to a new domain name that we own.
If I've got several existing servers, can I safely register them in another
domain while they're actively registerd in another?

Also, we've got one secondary DNS server in another domain run by a friend.
Could I register that server's IP address as a name server in one of may
domains?  Is this wise or something to avoid?  Of course, I'd need to be kept
abreast of any IP changes should he decide to move that server, so that I could
update it in my own domain, but the server hasn't moved in years and is
unlikely to in the future.

What I'd like to do is change the following:

ns1.ourpreviousdomainname.com = 192.168.46.115
ns2.ourpreviousdomainname.com = 192.168.46.116
ns1.myfriendsdomainname.com   = 10.0.14.203

to

ns1.newname.com = 192.168.46.115
ns2.newname.com = 192.168.46.116
ns3.newname.com = 10.0.14.203
