To my understanding, every time someone is hosting a service e.g. mysql server, there is always a server IP (or domain name) and a Port needed to reach the service (e.g. www.servername.com:3306).
However, when I access sites such as www.google.com or www.wikipedia.org, I 've no idea what port I am connecting to.
For instance, none of the following links www.google.com:80, www.google.com:8080 work, and the case is the same for wikipedia. So the question is:
Is there a port already "embedded" in links such as google or wikipedia, or have I just not found the default port yet (i.e. it is not 80 or 8080)?
Is there a general way to break a link www.somewebsite.com into a host + port combination in the form of www.somelink.com:[PORT] ?
