Netstat -an command output TCP [::]:135 [::]:0 LISTENING

In my InfoSec course assignment, we were given the task to analyze the different communications that were displayed when we run the command netstat -an. While analyzing I saw the following communication: TCP [::]:135 [::]:0 LISTENING, which I have not really encountered before and do not know how to interpret. I searched for the answer on the web and couldn't find much information related to my specific question.
