IP exclusion currently limited to wildcards, e.g., 128.252.135.*
Support for CIDR notation would allow for the equivalent 220.127.116.11/24, but also allow for things harder to express using wildcards, e.g., 18.104.22.168/21.
Wildcards and / or a combination of listing specific IP addresses will meet all use cases for IP exclusion within a company.
Wildcards are limited to representing /24, /16, and /8.
