Not sure I understand...

If you change the IPs assigned in DNS, then the clients connection via
those names will simply use the new IPs.

Why do you think that would cause a failure?

We have two DNS entries, one for Production LPAR and one for R&D LPAR.
Each DNS entry point to our original IP.

Pencor05.pencor.com points to x.x.x.5
Pencor06.pencor.com points to x.x.x.6.

We have a 2nd IP on each LPAR, going through a 2nd firewall.

We'd like to change the two DNS entries to point to the newer, more secure
IP.
Things will fail.

Is it possible to determine who or what is using these DNS entries?.

I probably need the network folks to create 2 new DNS entries for each of
the new IPs.

Anyone ever go through this exercise.

Thank You
