listening to local ports

i am confused. which is google cloud server is listening to my local ports, for example on port 139, which is net bios, but port test, label all ports as stealth, so how it can listen, i am not using google cloud, or anything.
It appears sometimes under local address instead of local hostname, how one machine can have multiple hostnames ?
And appears to listening on ports for origin for example, which is platform for pc games and other software.
It was previously
When i blocked this hostname in hosts file, everywhere started to appear this hostname
What google has to do with all these applications.
I could block all google addresses, but no gmail :smiley:
I just curious.
Thanks for answer.
