The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
So you have a single DNS store that contains multiple entries for your POWER server with different IP addresses and you want to know what clients are using specific host names? You might be able to monitor the DNS server for lookup requests.
Are the clients on the same subnet and using different routes to get to your server?

Subject: How does one determine who is using a DNS entry
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
