There are a few options that need to be considered when choosing a proxy from a list. Those options include port numbers, proxy types, SSL, country, latency, and reliability. Most proxy servers off all of some of these options to subscribers.
There are 65,000+ ports, which include well-known ports, dynamic/private ports, and Registered ports. Because there are so many ports, most proxy services offer you a range of ports to choose from before you connect to their proxy. Those options are 1-1023 for well known ports, 1024-49151 for registered ports, and 49152-65535 for registered ports. Choosing a port is dependent on your security system and which ports you have open on your computer. Usually the best choice is 1-1023.
The Types of Proxy:
There are a bunch of different types of proxy, and each does something slightly different than its counterparts. For example, you have http and https proxies you also have anonymous, transparent, non-anonymous proxies, and non-transparent proxies. Then you have the socks proxies, Etc.
Most people need to be anonymous which is why they are using a proxy in the first place.
SSL or secure socket layers are a web browser feature. Whether or not you need SSL is dependent up on the server that you are going to use. Some require SSL certification and others do not. IF you try to log on, you should be notified if SSL is required. Simply go back and engage SSL if needed. Some proxies use SSL automatically.
Because of censorship and geological barriers enforced by Internet Services Providers it is sometime difficult to access websites behind barriers. To get around that choose a service that is within the country that you wish your computer to browse. Logging into a server within that country will remove all of the geographic barriers and allow you access to most restricted sites.
Latency simply means the speed in which a packet of data can be manipulated and read by your computer. Lower is fast in terms of numbers, so 1 is faster than 2. You choose the latency based on your needs. If you are downloading larger files, than faster is better.
This is a measure of how reliable the server you choose is going to be. This is based on statistical data, and is often shown as a percentage of time that the proxy is reliable. Higher percentages mean higher reliability, and lower percentages mean less reliability.
Once you have opted for all of the choices you need the proxy to do for your computer, you will be provided a choice of proxies to choose from based on your option list. Simply choose the proxy that works best for you and connect to the Internet.
