DHCP listens for incoming on UDP 67 and send out on UDP 68 For 'well known' and 'registered' ports, you can check http://www.iana.org/assignments/port-numbers too. by gerson.freire@terra.com.br
ephemeral port numbers and well known port numbers
Ephemeral port numbers and well-known port numbers.
Short answer: Buying a domain name. Longer answer: A URL is created by typing in a string of the form: scheme://domain:port/path?query_string#fragment_id One popular scheme is known as HTTP (hypertext transfer protocol). The "domain" portion, as suggested above, refers to the domain name associated with a compute through the registration in the Domain Name Server (DNS). The "port" can often be inferred from the scheme, where standard ports have been allocated. The "path" is the reference to the particular file to be found on the computer using the IP address obtained from the domain name through the DNS, and accessed through the port, using the scheme.
Domain names are host name which gives identity to Internet Protocol on internet. There are more than 2 crore websites at present and searching and memorizing a website is very difficult if it have IP Address with some numbers only. So Domain Name System's (DNS) rules and procedures are followed while giving a name to the website. The domains are registered with the Domain Registrar who governs and administer the domains. Simplified: If we did not use domain names, you would have to type a string of numbers (an IP address) to get to any website. For most websites, you would also have to type a port number and / or a user or file name. Example (actual IP not used): "67.196.138.62/~answers" or something similar would be used to access the home page of the answers website. Most modern websites have the ability to access them with an IP address disabled for the public. So I guess the true answer is, you wouldn't be able to access many sites at all without domain names.
TCP port numbers, as well as UDP port numbers, are 2-byte numbers, therefore, the range is from 0 to 65535.

You cannot directly access the parallel port because the operating system is managing that device. Use the file system. The name of the parallel port is "lpt1:". Open that as an ordinary file for write, write to it, and you will be writing on the parallel port.
The server address is rather an IP address or a domain name used to connect to a public server. Most servers end in the port *:25565
