Edit Question
Title
Body
I have ~12600 subnets: eg. 123.123.208.0/20 and an IP. I can use a SQLite Database or an array or whatever There was a similar question asked about a month ago, however I am not looking for checking one IP against one subnet but a bunch of subnets (obviously the most efficient way, hopefully not O(total subnets)) :) How can I check that the IP is one of in one of these subnets, I need true or false not the subnet if that helps optimisation. There are similar subnets in the current list eg.: (actual extract) 123.123.48.0/22 <-- not a typo 123.123.48.0/24 <-- not a typo 123.123.90.0/24 123.123.91.0/24 123.123.217.0/24 In total they range from 4.x.y.z to 222.x.y.z
