Folks,
Our normal procedure when changing the IP address of a TLD name
server is to get the new server responding properly and then update the glue
records with the Registrar to reflect the new address, normally 1-2 days apart
for two nameservers. We monitor query traffic on each and usually see a
distinctive shift once the glue record is updated and almost all traffic shifts
in the first 24 hours. e.g.
ns1.example .com - 1.2.3.4 (first day) --> 10.20.30.40
(confirm normal ops)
ns2.example.com-5.6.7.8 (second day) --> 50.60.70.80
We had someone on staff make a suggestion we could modify this
approach by adding an additional IP address for each of the existing servers:
ns1.example.dom - 1.2.3.4 (first day) --> 1.2.3.4 & 10.20.30.40
(confirm normal ops)
I never even thought a Registrar would allow this? Is it
supported? A useful idea in certain scenarios (although I'm not sure when) ?
Thanks!
