Local port: NLP(?)

Checking my TCPView directly when I plugged in the internet cable I noticed a svchost.exe appeared in TCPView list and the Local Port said, from what I remember - NLP. This dissapeared the next second. But googling I havent found anything, assuming that I didnt saw NLP but another very closely abbreviation.

 

Any idea what this was? Is there any Local port using like NP, npl etc?
