Hello,

You can. host() just extract IP address from a value of inet
type as text, string_to_array() converts this text to text[], and
it makes it possible to compare with another text[]... I see no

But probably there is another (better) solution...

I will be glad to see the best solution, so if you find it please share. :-)
But you want to compare IP addresses by 3 first parts. I don't see any
function or operator at SQL level which allow to do it without converting
to text.
Probably, you can do it by manipulating a binary form (from

regression=# select network(set_masklen('123.45.67.42'::inet, 24)) =

Thank you. Or maybe also?
