Dynamic IP - pg_hba

Hi!

How do I configure acess to Postgres for a number of clients that use
dynamic IP-addresses? The configuration (Postgres 7.2.3, RH 8, W2K clients)
works and clients can connect with the host fine with static IP-addresses.

I think I need to update the pg_hba.conf file with some type of pattern that
will be matches @ runtime but I can't figure out the format of the entries.
Can some1 send me a sample pg_hba file, or suggest the matching rules?


Thanx!

-Dirk
