IP address range question. Tags: IP IP Address Networking Last response: May 6, 2007 12:08 PM in Networking Share birko19 May 4, 2007 9:36:29 PM Hi, my first post here I have a question that might sound stupid but I come from a software programming background and currently I'm working on a project that involves some IP range checking, so here's my issue. Let's assume a this is the range case we have: 1.2.10-20.30-40 What IP addresses would fit that range and which ones would not fit the range, let me give you some IP examples and please tell me which one fits in and which one does't: 22.214.171.124 126.96.36.199 188.8.131.52 184.108.40.206 My understanding is the IP range that I provided contains the IP addresses in the following order: 220.127.116.11 18.104.22.168 22.214.171.124 126.96.36.199 . . . 188.8.131.52 184.108.40.206 . . . And so on... But my workmates tell me this is what it means: 220.127.116.11 18.104.22.168 22.214.171.124 . . . 126.96.36.199 . . . 188.8.131.52 184.108.40.206 220.127.116.11 . . . 18.104.22.168 . . . 22.214.171.124 126.96.36.199 188.8.131.52 . . . 184.108.40.206 End. I'm sorry if I was't very clear, but this is a very confussing case I'm working with right now, so please bare with my explenation....

That means you are correct in your interpretation. Can't find your answer ? Ask !
