Sheesh, arbitrary restrictions ;-) Something like this then:
CREATE FUNCTION inet2num(inet) RETURNS numeric AS $$
DECLARE a text[] := string_to_array(host($1), '.');
BEGIN RETURN a[1]::numeric * 16777216 + a[2]::numeric * 65536 + a[3]::numeric * 256 +
a[4]::numeric;
END;
$$ LANGUAGE plpgsql IMMUTABLE STRICT;
