Port

If you are concern about your privacy using only one proxy server then is Proxy Chaining probably more attractive method. Proxy Chain stand for using several proxy servers in chain before you reach your final destination.
More proxy server in chain and it will be harder to trace you back but your connection speed will be slower too. Another drawback is that if one proxy server during chaining process become unavailable then is chaining not possible.

TCP/IP protocols and Port Number

In IP TCP and UDP networks, a port is an endpoint to a logical connection and the way a client program specifies a specific server program on a computer in a network. Some ports have numbers that are preassigned to them and these are known as well-known ports.

Other 2 groups are Registered Ports and Private Ports. Private ports are also called dynamical ports.

As you probably know port ranges are all ranges between 0 and 65535. Between these 3 groups are port numbers divided. Well-known ports have range between 0 and 1023.

Registered ports have range between 1024 and 49151
And Private ports are not definited and assigned to any applications and they occupied range between 49152 and 65535.

IANA (Internet Assigned Numbers Authority) did official designation of TCP and UDP ports numbers. Most common proxy server ports are 3128, 8080, 80 and socks server ports 1080.

But proxy can be specified on any other ports. On other 2-3 pages inside TCP/IP protocols thema we will try to give explanation about TCP and UDP ports and display all ports that are used by well-known trojan horses applications.
