Display Users
To display all configured users;
SELECT CONCAT('SHOW GRANTS FOR \'', user ,'\'@\'', host, '\';') FROM mysql.user

Data Types
IP Addresses
IP addresses are most efficiently stored as an UNSIGNED INT, though obviously this isn't particularly human readable. MySQL will do the conversion between INT and dotted quad using the INET_ATON and INET_NTOA functions. For example;
SELECT INET_NTOA(ip) from ips;INSERT INTO ips SET ip=INET_ATON('10.1.2.3');
Alternatively, use VARCHAR(15) to store as text.
