We currently have 2 internet connections.
Our DNS' are on connection "A"
Our Web servers are on connection "B"
The reverse for connection "B" is delegated to our DNS' on connection "A"
We are moving the DNS' to connection "B"
We have processed a host change that will go into effect with the 5am
update.
Will the reverse move with the host records or do we need to inform our
connection "B" provider that we've update the IPs?

In article <9oto1s$3...@pub3.rc.vix.com>,

Delegation NS records point to names, not IPs. If the names of your
nameservers are not changing, ISP B doesn't need to change the delegation
records of the reverse domain.

However, if ISP B's nameservers are also configured as slaves for your
reverse zones, then they will need to update their named.conf files, since
"masters" statements contain IPs, not names.

What does your "connection 'B' provider" have to do with your DNS? Are they
a slave? If so, then they'll need to know the new address of the master.
Otherwise, it's totally up to you to update the A and PTR records in your
zone(s).

"Connection B" provider delegates the reverse to our DNS'. I'll have to
check with them to see if they are running as a slave.

Provider B presumably operates the master nameserver for y.z.in-addr.arpa,
and is delegating x.y.z.in-addr.arpa to the customer's nameservers.

Well, delegations are done with names, not IP addresses directly. So if you
control the names of those nameservers, then this shouldn't be a problem.
