Isass.exe

When viewing Norton's Security History, I noticed this entry this afternoon:  Firewall rules were automatically created for Isass.

 

Advance details are:

Program name:  Isass

Default action:  Learn application

Action taken:  Learn application

Program path is c:/windows/system32/Isass.exe

Traffic description:  Outbound UDP, 53

Isass was allowed to communicate with xxx.47

 

The remote computer IP address is almost identical to mine except for:

Mine: xxx.1

Remote computer:  xxx.47

 

My dumb question:  Is my computer communicating with my ISP provider or is this something I need to be concerned about?

 

The only thing different I noticed while on the internet was when I was checking out the latest news on CBS News and a box appeared asking for my user name and password.  I hit cancel.  Other than that, my surfing was just to the normal sites I go to everyday.
