*EDIT* This has been implemented in 2020.2!
We just had an issue while trying to add 244 subnets to an IP Address group to classify Zoom traffic. Their website provides their subnets in a list that contains CIDR notation, so I had to translate each of them manually. Got to brush up on my subnetting! Because I was typing the end range manually, there ended up being a typo. Instead of the range 188.8.131.52 - 184.108.40.206, my end range IP ended up being 220.127.116.11 which caused quite a bit of confusion when a bunch of Google Meet endpoints (18.104.22.168/24) got gobbled up in this IP Address Group.This is what I'd love to see:
