Understanding the Port Number in DNS URLs
When you encounter a DNS URL, you may notice an optional port number appended to it.
By default, most URLs use port 80.
If you don't see ":80" at the end of your URL, don't worry—the application you're using will automatically add it for you.
However, if you come across a URL with a port number other than 80, it's crucial to include that specific port number when typing in the URL.
Otherwise, your connection may not work as expected.
In summary, the default port is 80.
If it's specified in the URL, you must include it; if it's not, the application will handle it for you.
