Several applications trying to connect to IP I have several applications on my computer which are attempting to connect to a small hand-full of IPs over port 80(http). This seems suspect to me and I'm not sure how to proceed. Currently I am using Little Snitch to block the IPs however this is causing some things to not work.

IPs in question:


151.205.0.101
151.205.0.103
151.205.0.105
151.205.0.107


Looking up these IPs on Who.is reveals they are owned MCI Communications Services, Inc. d/b/a Verizon Business (MCICS)

The applications I have seen trying to connect to these IPs


Private Internet Access, Although it has since stopped since I updated it to the latest version.

Google Chrome

ksfetch
vmnet-natd
ScreenSaverEngine


I believe I have seen other applications in the past attempt to connect to these IPs, however, the ones above are attempting to as of me writing this.

What could be causing all of these seemingly unrelated applications to try to connect to these IPs?
All these applications need the DNS (Domain Name System) to translate Internet names into their IP address, and the reverse.

The IP you found are the one of the DNS servers of Verizon.
The following command will show it clearly:

 dig -x 151.205.0.101


Your udp and tcp exiting traffic toward DNS port = 53 should be permitted.

Fix your Little Snitch configuration so that all your DNS traffic could pass.
