[feature] Add External IP to filtering

[KCarretto]

Maybe this would be useful?

" Figuring out what teams I have is challenging because I can't sort by IP" - @jabbate19

This is because we only have filtering for primary ip and you needed external ip. Help us out? 🥺🙏

External may not help with filtering by team by IP but it is helpful for real red teaming to see if different segments have different egress. We're gonna focus egress on this external IP so the other one doesn't get caught if an alert fires.
