We need to move our Primary DNS server from legacy IP space provided by =
our
upstreams to our ARIN Assigned IP space. I am looking for advice and =
any
gotchas. I couldn't find any white papers to this affect or archived
articles or postings. If someone does have a resource for this or find =
this
could be valuable, I can certainly gather all the info and document it.
Most of the Registrars I have seen now use the Authoritative DNS Server =
Host
names for the domain name registrations vs the IP Address. For most of =
our
customers, we register and host the DNS. I have confirmed almost all =
the
customers have either Network Solutions, Tucows, Go Daddy and =
Register.com.

Can I simply change the IP address of our DNS server and update the DNS =
Host
Record with our registrar with the new IP and any A / NS records we have =
?
As long as other customers domains have our DNS Server FQDN as the Host,
they should not need to make any changes, correct ? I would love to =
think
its that simple, but there is always a gotcha. Does anyone know of any =
main
registries using just the IP Address where the customer might need to go =
in
and make those changes for each and every domain ? Any input, advice or
ideas is appreciated.
