Need help with Inet type

Hi,

I would like to know if there is a way to do what I need with
Postgress.

I have a table with logs and a table with a list of subnets.

Right now I do the following query in my table:

Select * From logs Where src_ip << '10.0.0.0/24' OR src_ip <<
'10.1.0.0/24' OR src_ip << '172.168.1.0/28';

I would like to simplify that query and use a table instead as the
source of the subnet I want to check.

I have a table that contain a list of subnet and zone name:

ZONE_a 10.0.0.0/24
ZONE_a 10.1.0.0/24
ZONE_a 172.16.1.0/28
ZONE_b 10.2.0.0/24
ZONE_b 10.3.0.0/24

I can do something like:

Select * From logs Where src_ip IN (Select ip from ip_table where zone
= 'ZONE_a');

Of course that does not work since it does not work with Inet type and
I cannot use << because I have more than 1 row return from the second
select.

Is there a way to achive that?

Thanks.
