I would like to know if there is a list of well known public IP groups. Not a group such as the range owned by google but more specific, I.e. the servers google uses for youtube.
When I run a few youtube videos on my test network I see the traffic but the IP addresses listed under top 5 endpoints are not registered to a domain so I can't see that the traffic is going to youtube.com, instead it shows 173.194.5.* address. Now I can add these to a group called youtube but I have no idea if these servers are used for google earth or another application.
Any help with this would be greatly appreciated.
