Every Unix/Linux system has a file, /etc/services, which contains the "well-known" ports. However, if your system is not on the public network (the Internet), you can use any port number above 1024. Ports are the second part of an address. A service on a  specific IP address, like 192.9.200.1, may listen for connections on ports from 1 (zero is reserved) to 65535. This allows an IP address to have multiple services like mail, telnet, etc., all the "services" listed in /etc/services.

A lot of predefined ports already down there easier to hide up above
