inet data type and select

Hello.

I'm busy writing an IP accounting DB using nacctd and postgres.
The data gets inserted correctly into the database and I can run the
select queries that I desire.

e.g. (select sum(size) from iptraff where srcip = "209.100.30.2") gives
me the total bytes that that particular host sent. Now it would be
*REALLY* groovy if I could do the following: (select sum(size) from
iptraff where scrip = "209.100.30.0/24")
That would tell me the total traffic for that subnet.

>From what I understand the relevant code resides in network.c
unfortunately I am not a C person :-( Perhaps this feature would be
included in the next snapshot/release or someone could help me with my
particular installation.

Thanks!
