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.
Thanks
Eric
