Security history - software loopback interface 1"

Hi,

 

When I look in security history I have the usual software loopback interface 1 " ( IP adress: 127.0.0.1 ) but there is another entry and the IP address :: 1

 

Please can anyone tell me if this normal or common?

 

Oh, sorry NIS 2012 19.9.1.14

 

One more thing.. this :: 1 IP has been there for quite a long time now.
