Hi Josh,
Ok, first the explain analyze ....

June_03=# explain analyze select * from tmp where route
>>='62.1.1.0/24';
QUERY PLAN
-----------------------------------------------------------------------------------------------------------
Seq Scan on tmp (cost=0.00..606.60 rows=14544 width=33) (actual
time=3.862..15.366 rows=1 loops=1)
Filter: (route >>= '62.1.1.0/24'::cidr)
Total runtime: 15.493 ms
(3 rows)

And the version of postgres

June_03=# select version();
version
--------------------------------------------------------------------------------------------------------------------
PostgreSQL 7.4.1 on i686-pc-linux-gnu, compiled by GCC gcc (GCC)
3.3.2 20031022 (Gentoo Linux 3.3.2-r2, propolice)
(1 row)

Thanks,
Georgos
