Postgres Check if IP (inet) is IN a list of IP Ranges

Question

I want to check if an IP exists in a range of ranges, eg: SELECT * FROM ip_address WHERE ip IN (<list of ip ranges>)

Postgresql documentation states to use the << operator to check if an IP is contained within a single IP Range, eg: inet '192.168.1.5' << inet '192.168.1/24', but I'm not sure how to use it on a list of ranges without having to construct an OR chain of <<'s.

Answer 1

select inet '192.168.1.5' << any (array['192.168.1/24', '10/8']::inet[]);
