Using ip.host matches "^10\." doesn't recognize \. as a period [closed]
I'm trying to filter Ip addresses by certain parts. For example, I want to get all Ip addresses where the first octet is 10. The problem is that when I try ip.host matches "^10." its also brings up all addresses that start with 100-109. For example, if I was searching using ip.host matches "^10." and would bring up 10.0.0.1, but it might also bring up 104.0.0.1. The desired result would be for it to only bring up addresses that have 10 in the first octet.
How do I get the desired result?
