To get a host name associated with an IP Address, you probably want
to use the gethostbyaddr API from the Sockets (Unix-Type) API stuff.

Likewise, you can use the gethostbyname API to get the IP address,
or alternate host names for a given host name.

Can you do it in an RPG/400 program? No. But you CAN do it in RPG IV
(ILE RPG/400) if you're familiar with the basics of converting C
prototypes and data structures to RPG :)

It'd be pretty much impossible to do in CL (even ILE CL) because of
the pointer logic thats involved.  So, I'd really recommend either
using RPG IV or ILE C/400.

If you'd like an example in RPG IV, let me know...
