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;
