Storing the IP addresses as integers requires less memory but incurrs the cost of a call to these functions for every IP address. If you are going to use these addresses in string comparisons it's best to store them as varchars.

I'm logging IP addresses and also searching for existing ones. Does anyone happen to know which is more resource intensive: storing the IP's as integers using INET_NTOA() and INET_ATON() to convert them at each query; or simply storing the IP as a varchar? In each case the IP field would be the primary key.
