I use sorted sets quite heavily for timelines. And it's awesome.
One usecase I can't figure out, is storing/querying IP address ranges. Is there a natural way with Redis to check if a number is within a given range? (without storing every value and without multiple calls)
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.
