What is the best way to store IPv6 address in Hive?

[Igor Kuzmenko]

Currently I'm using ORC transactional tables, and i need to store a lot of
data containing IP addresses.
With IPv4 it can be a Integer (4 bytes exacty), but what about IPv6?
Obiously it should be space efficient and easy to search for exact match.
As extra feature it would be good to do fast search with mask (10.120.*.*)
