Can one safely block 22.214.171.124, 126.96.36.199, &c . . . 188.8.131.52
I use Little Snitch which shows Firefox allowing connections to 8 IP addresses that, for not seeing a reason, I blocked in LS. Nevertheless, LS lets about 10% of those connections through, so I police and disconnect. On the net, I found that those IPs belong to Level3 Communications which has a bad rep among some. I contacted the Little Snitch people who advised that I was wrong & the real owner is google (not really an answer to why their program lets through even after I've blocked). But here's the thing -- I use google ONLY for e-mail; I don't want to place my computer at their disposal for anything else. SO, should I continue my blocking campaign, or let the eight IPs through. My concern is Privacy and Security.

184.108.40.206 I know in the US is the open google dns. I am not familiar with the 4.x.x.x. Each time a url is visited, or a new site the dns is contacted to convert that url name to an ip address of that website.
Some tools to use to tell whois these ip addresses. Just enter the ip address here: http://mxtoolbox.com/DNSLookup.aspx
That are are the IP addresses of public DNS services.
