INET contains question

Hello,

I have a table that contains a two columns of type inet. One is an address one
is a network. Due to an error in an application there are some rows where the
address is not contained in the network. So I did a:
select sourceip,whoisnet,dnsnet from attacks where not (sourceip << whoisnet);

which is more or less right but in the cases where the whoisnet is not a class
a/b/c-network I also get a match which is not correct. Is this supposed to be
so or a bug?

I am using 7.1 on Linux to do this.
