Mac – How to find who is connected to the computer from MAC address

mac addressnetstatport

When I type in the command netstat -an into cmd, I get information that one of my ports is opened from some MAC address. My qestion is how to close that port and how to find from the MAC address what ip the other computer has?

I get this output: 

UDP    [fe80::b970:58f1:a42a:a333%11]:1900  *:*
UDP    [fe80::b970:58f1:a42a:a333%11]:50524  *:*

Looking at your output, I don't think those are MAC addresses. Rather they are IPv6 addresses. Also, I think the carriage returns got mangled in your question. I don't think that it is showing any computers connected, rather just that you have process(es) listening on those ports.

To find out what Windows process is involved, you can do a netstat -anb (you may have to do this with Administrator priviledges).

Port 1900 is used for the ssdp protocol. You could turn this off by disabling the SSDP Discovery service.

I'm not sure what corresponds to port 50524, but on my system, that same SSDP Discovery service is listening on a number of high numbered ports... it may be the same for you.
