In a nutshell, port 53 is used for DNS, which basically converts fully qualified domian names (the website address you type into a browser) into the actual IP address for that site.

 

That port is (or should be) open by default.

Thank you for sharing some of your information. So it's like a convertor in order for you to access websites.  :thumbup2:

 So if this port 53 is disabled or closed, are there still websites you can access?

Unless you are "hosting" those website on your computer, not really. You would need to know the IP address of every website you wanted to visit.

Why do you want to mess with this port?  Do you understand if you disable it you also disable your internet access?

Nothing to learn with this port.  If you want to learn about port forwarding bring up a minecraft server.  Google and learn the difference between well known ports,  and registered ports.  Learn the OSI model and what layer internet port sockets exist at.  This will be valuable. Opening and closing the dns port isn't productive.
