John,
Yes, you can use hostnames in your tnsnames.ora file instead of IP addresses. We are doing so with Oracle 7.3.4 on Sun Solaris 2.6.
As long as your DNS is resolving the host names to the IP addresses correctly, you should have no problem.

Hello Gurus:
We are in the process of changing over our IP addressing scheme to a private network behind a firewall. This meant that all out servers are going to get new IP addresses. I know that our TNSNames file has IP addresses in it that will have to be changed. What other places will I have to look to make sure everything still works when we switch? Is it possible (advisable) to replace the IP address with a DNS hostname?
We are running Oracle 7.3.4 on HP/UX and OAS 4.x on a Sun Enterprise 450
Thanks
JG
