An IPv4 address is a 32 bit unsigned integer. The "string of 15 characters" is a human-readable representation of it. AFAICT the context was obtaining an efficient packing of the data in question (see the post on binary logging to a database). I chose the IP address as an example -- the ID being created was not even close to what we had been discussing and what Matt implemented and I did not want to go in to length on an example which appeared to be marginally on-topic. -- --gh
