store ip ranges in Redis

Question

I have a lot of IP ranges of different providers. For example

P1: 192.168.1.10 - 192.168.1.50, 192.168.2.16 - 192.168.2.49,
P2: 17.36.15.34 - 17.36.15.255,
P3: .         


        

Answer 1

This is similar to what Didier Spezia proposed, but we use begin range and end range in sorted set, because there may be "gaps".
