I know it blocks braze because an app I was testing it in an app I was developing. It's possible for them to hardcode IPs, but last time I checked they were too lazy for that. Maybe static IPs still cost extra? Some apps will do one DNS query and cache the IP they get, so maybe what you're seeing is them using IPs they cached before you rigged up this custom network situation.
