What about the other way around though? Storing the range, say, 159.18.0.0 - 159.18.255.255, and then querying to check if an address is in that range.
The only way I can think to do this is to store the range as two integers, as you suggest, and query twice. The first to find the nearest lower bound for an IP and then a second time for the upper bound.
