As already mentioned inet / cidr types should work. Example:
postgres=# create table inettest (a inet);
CREATE TABLE
postgres=# insert into inettest values
('192.168.0.1'),('192.168.1.1'),('10.0.0.1');
INSERT 0 3
postgres=# select a from inettest where '192.168.0.1/16' >> a;
a
-------------
192.168.0.1
192.168.1.1
(2 rows)
postgres=# select a from inettest where '192.168.0.1/24' >> a;
a
-------------
192.168.0.1
(1 row)
postgres=# select a from inettest where '192.168.0.1/0' >> a;
a
-------------
192.168.0.1
192.168.1.1
10.0.0.1
(3 rows)
