No, they're not. The first thing I always do is to un-check that option. The screenshot provided was taken when that option was clear too. Any other ideas?
With other run I may get other, but similar connections. If I resolve those connections and block corresponding IP's with firewall. It will try to connect to different servers. One of them I've mentioned in my earlier post:
IP = 18.104.22.168, which could be referred as google-analytics.com or pd-in-f106.1e100.net.
Keep it simple, it'll become complex by itself...
