I only sent in tests for the functions I added. Ok, add the following two INSERT statements. INSERT INTO INET_TBL (c, i) VALUES ('10', '11.1.2.3/8'); INSERT INTO INET_TBL (c, i) VALUES ('10', '9.1.2.3/8'); Then add the following query. SELECT i, c, i < c AS lt, i <= c AS le, i = c AS eq, i >= c AS ge, i > c AS gt, i <> c AS ne, i << c ASsb, i <<= c AS sbe, i >> c AS sup, i >>= c AS spe FROM INET_TBL; -- D'Arcy J.M.
