New events in History: “Software loopback Interface1”(IP :::1),connection protected network(:::0)

Norton Security | Norton Internet Security
1

In NIS History: 3 entries appeared for the first time at last startup. Software “loopback Interface 1” (IP address: :::1), connection protected network (:::0) another instance of “loopback interface 1”. See pictures below. They are listed in the order appearing in history log. All 3 new events occur just before loading the expected network wireless adapter (picture 4). Nothing changed in network set up. Pics in order loaded and order  from History log.

Picture 1: connected to protected network (::0).

Picture 2 – show a “Software Loopback Interface 1” (IPaddress 127.0.0.1).  The IP 127.0.0.1 is not new to history, but  it was protected never under “Software Loopback Interface 1”.

Picture 3 - Another Software Loopback Interface, this time for IP ::::1. ??? 

Picture 4 – the normal event (always in History each startup) initializing the Network Wireless Adapter

 

Questions:

1-     Why the 3 new (their first time seen in NIS History events (Pic 1, 2 and 3)?  What does it mean?

2-     What mean: connected to protected (::0)?             (:::0) ???

3-     What mean: “Software Loopback Interface 1” (IP address 127.0.0.1)” ?

4-     What mean: “Software Loopback Interface 1” (: :::1) ?  (:::1) ????

BTW When you said your images did not upload did you use the Insert/edit image icon in the toolbar of this editor?

 

Then Browse to locate the file on your hard drive and follow the instructions?

 

Images do not appear immediately but only after checking by moderators but they do leave a placemark until cleared.

Hi TestingABCD,

 

The Loopback Interface is an internal network that software uses.  127.0.0.1 is the IPv4 address, ::1 is IPv6.  "Protected" is Norton's Network Trust Level that it has assigned to the network, and corresponds to the group of firewall rules that are being applied to monitor the traffic.  This is all normal and nothing to be concerned about - I don't know why you haven't seen it before, because the loopback interface should always be there.
