Doing a netstat -b -f revealed my browser connects a few times to *.1e100.net, a domain as popular as Google.com. A whois search reveals something I never knew about google…
1e100.net is a Google-owned domain name used to identify the servers in our network.
In true Google style it ultimately has a sensible origin.
Most typical Internet users will never see 1e100.net, but we picked a Googley name for it just in case (1e100 is scientific notation for 1 googol)..
Apparently where Google got its name too..
