Of course.  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', '');
INSERT INTO INET_TBL (c, i) VALUES ('10', ''); 

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 AS sb, i <<= c AS sbe, i >> c AS sup, i >>= c AS spe
