Hello, I'm trying to check an IP against a list of several CIDR ranges, so far the most obvious way to do it seems to parse both the IP and the cidr ranges ( ParseCIDR) and then do a net.contain() however, if we have more than 1 CIDR we have to loop checking one by one which imho is incredible unefficient + slow if the cidr range is big.
Is there any more efficient way of achieving this? I have thought on making a map[string]string with all the IPs (within the CIDR) but the amount of required memory for big lists goes up to a few GB.
