Yes, I reproduced this (Solaris 2.5/sparc).
Seems like CIDR problem(??!):
ais=> create table test (zone int4, net int4, unique(zone, net));
^^^^
NOTICE: CREATE TABLE/UNIQUE will create implicit index 'test_zone_key' for table 'test'
CREATE
ais=> insert into test (zone, net) values (1, 1);
INSERT 7712479 1
ais=> insert into test (zone, net) values (1, 2);
INSERT 7712480 1
ais=> insert into test (zone, net) values (1, 1);
ERROR: Cannot insert a duplicate key into a unique index
