Hi
I have queries that use like operators and regex patterns to
determine if an ip address is internal or external (this is against
a table with say 100 million distinct ip addresses).
Does the inet data type offer comparison/search performance
benefits over plain text for ip addresses..
It's probably better than text-based, but it's hard to be worse than
regex and like.
Depending on your exact needs http://pgfoundry.org/projects/ip4r/ may be
interesting, and I've also found pretty good behavior by mapping an IP
address onto a 2^31 offset integer.
