What is the difference between 8443 and 443?
Likewise, people ask, is Port 8443 and 443 the same?
8443 is an alternative for 443. 443 is a secure port for https. Not much difference between the two.
One may also ask, why is port 443 open? When a port is open, there's server software on a computer running and listening for connections to that port. If port 443 is open on a computer, that usually means web servers are waiting for a connection from a web browser. If some service other than a normal web server is using port 443, this process may fail.
Moreover, is https always port 443?
Because data can be sent with or without the use of SSL, one way to indicate a secure connection is by the port number. By default, HTTPS connections use TCP port 443. HTTP, the unsecure protocol, uses port 80.
What are ports 80 and 443 used for?
Port 80 and 443 are ports generally associated with "the Internet". Port 443/HTTPS is the HTTP protocol over TLS/SSL. Port 80/HTTP is the World Wide Web. Let's face it, port 80/443 are generally a given for being open on any type of filtering device allowing traffic outbound on your network.
