Simply convert them to a binary representation using
inet_pton()and later back to a string usinginet_ntop().Another solution would be storing the IP string without any transformations in the DB. A
VARCHAR(39)field will do the job as the highest/longest IPv6 isffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff
