When I look at all the ports that are open on my computer, one of them is 53
, which corresponds to DNS.
From what I understand about how DNS stuff works, my computer would normally have to ask someone else about domain name information - my ISP would be my DNS.
But if my DNS port is open (in a LISTEN
state), then what does that mean? That I'm a DNS service to some other device? Are other phones on my WiFi trying to reach my computer first for DNS info before they get forwarded to the ISP's DNS, or what?
