cidr data type question

[Vasiliy G Tolstov]

Hello.
I have table with cidr data type column (table is white/black list of
networks).

Does it possible to query - is the some address contains in any cidr
network in this table? (for all networks in the table do "contains or
equals"
http://www.postgresql.org/docs/8.4/interactive/functions-net.html
)

    SELECT * FRMO mytable WHERE mytable.network >>= $1::INET;

that will return all rows of mytable which have a subnet that includes
the IP or subnet $1

If you mess with IP addresses, you should have a look at the ip4r
contrib module.  Since I discovered it, I've never looked back at
cidr/inet.
