Public Proxy VS Private Proxy

There are 2 types of proxy, public proxy and private proxy. Public proxy is open to public usage. Private proxy is only open to paid users.

There are two types of proxy, public proxy and private proxy. Public proxy is open to public usage. Private proxy is only open to paid users.

Public Proxy

Public proxy as known as open proxy is open to public usage. Every one can use it. Because of the lack of access control, the public proxy may be used by too many people. It makes the public proxy stop working if the number of users exceeds its capability. If a public proxy can be found easily on the Internet, it will die very fast. However it will work again when less people use it. Thus public proxy is usually unstable.

Though public proxy can usually keep working for only several hours, it has its advantages. You can find and use them for free. There are lots of public proxies on the Internet. You can use them to change your IP frequently. If you don’t know how to find them by yourself, you can buy our checked public proxy list. We update our public proxy list every day and check them from time to time. It ensures there are enough working proxies in the list.

Private Proxy

Private proxy is only open to paid users. You need to pay for the private proxy. It has good uptime. You usually need to input username and passord to use private proxy. The private proxy vendors control how long you can use their private proxy.

Our private proxy service is My IP Hide. It’s encrypted private proxy service. It can unblock websites (ex. Facebook and Youtube) as well as change your IP.

The private proxy service is available 24/7. It’s hosted on our dedicated servers. We monitor the status of them every minute. It ensures that our users can always use our service whenever they need.

Socks Proxy VS HTTP Proxy

A post about the difference between socks proxy and HTTP proxy, how to get, check and use socks proxy or HTTP proxy.

There are two types of proxy, socks proxy and HTTP proxy. When we say “proxy” or “proxy server” without the type, we are usually meaning HTTP proxy.

HTTP Proxy

The most proxies we find on the Internet are HTTP proxy. HTTP stands for HyperText Transfer Protocol which is used in surfing. It means HTTP proxy is used for surfing in browsers.

HTTP proxy may be configured to either reveal or hide the end user’s IP address, depending on the administrator’s preference. Proxy Anonymity is determined by whether or not the proxy reveals your real IP address.

There are three levels of HTTP proxy according to the anonymity.

Highly Anonymous Proxy (Level 1): The web server can’t detect whether you are using a proxy by the information your browser sent.
Anonymous Proxy (Level 2): The web server knows that you are probably using a proxy, but it can’t detect your real IP.
Transparent Proxy (Level 3): The web server knows that you are using a proxy and it can also detect your real IP address.

Socks Proxy

Socks proxy is a versatile proxy for all your Internet usage while the HTTP proxy can only be used for surfing. You can use socks proxy to send email, transfer files, chat online, play games as well as surf websites.

There are two versions of socks proxy: version 4 and 5, as known as socks4 and socks5. Socks5 supports UDP (VOIP needs it), name resolution, and authentication while Socks4 not. However, in most cases, you won’t use those features. Then Socks4 is same as Socks5.

Difference between Socks and HTTP Proxy

Socks proxy supports high anonymity and HTTPS (secure HTTP) naturally. All the socks proxies are highly anonymous. Every socks proxy support HTTPS websites (such as Paypal). You can hardly find HTTP proxies supporting both high anonymity and HTTPS.

There are two shortcomings of socks proxies. 1) Socks proxies are much less than HTTP proxies. 2) Fewer programs support socks proxy than HTTP proxy.

Use Socks Proxy and HTTP Proxy

Because proxies die fast, you need to check them before using them. You can use the free edition of our software Socks Proxy Checker or Elite Proxy Switcher to check the socks proxy or HTTP proxy.

Most browsers support both socks proxy and HTTP proxy. Double click the socks proxy or HTTP proxy in Socks Proxy Checker or Elite Proxy Switcher to set it as the active proxy for your browsers (IE, Chrome, and Firefox). Please read this post if you want to use socks proxy in other programs besides browsers.

Get Socks Proxy and HTTP Proxy

You can get some free socks proxy and HTTP proxy from us. You can also buy socks proxy and HTTP proxy list from us.

Free Proxy Die Quickly

Public proxies die fast. It’s usually because too many people are using them. If you need stable proxies, you can buy private proxies which are only open to paid users.

Usually, a proxy won’t live for long. It’s because too many people are using it. When you use a proxy, you are using the resource on the proxy server such as its CPU, memory, and bandwidth which are all limited.

Public Proxy

Most working proxies on the Internet are public proxy which is open to everyone. Because of the lack of access control, the working proxy will die if the number of users exceeds the capability of the server. If a working proxy can be found easily on the Internet, it usually lives very shortly.

Proxy Port and Proxy Type

It seems that the proxy port usually determines the proxy type. For example a proxy on the port 3128 is usually a HTTP proxy and a proxy with port 1080 is usually a Socks proxy. It’s because 3128/1080 is the default port of the proxy server software.

Default Proxy Port

Squid (a famous HTTP proxy server software) uses 3128 as its default port. So many proxies are on the port 3128. Many socks proxy server programs use 1080 as the default port. So many socks proxies are using the port 1080. However there are many proxy server programs using the different default port. For example, many proxy server programs use 8080 as the default port.

Common Proxy Port

There are the common proxy port which are used by most proxies.

HTTP Proxy: 80 443 808 3128 8080 8118
Socks Proxy: 1080 8080

There are some reasons why the proxy administrator choose those ports. The 80/443 port is the default for HTTP/HTTPS web server. Company won’t block those ports. 8080 is the HTTP alternate port which is commonly used for web proxy and caching server. 3128 is the default port of Squid. 8118 is the default port of Privoxy, an content-filtering HTTP proxy. I don’t know why so many proxies are on the port 808. Maybe it’s just because 808 is similar to 80 and 8080.

Possible Proxy Port

I checked our latest HTTP proxy list. There are 4476 proxies on the common port among the total 6523 proxies. The remaining 2047 proxies are on different ports. I compiled the ports that used by many proxies FYI.

Possible HTTP Port: 81 82 83 84 85 86 88 1337 3124 3127 3129 6515 6588 6666 6675 8000 8001 8008 8081 8082 8085 8088 8090 8123 8800 8888 8909 9000 9415 36081 54321 60099

I didn’t complied the possible ports of socks proxy. It’s because few of them use the same port except 1080 and 8080.

Judge Proxy Type

But you should know that proxy port absolutely depends on the settings of the proxy administrator. The admin can set a http proxy running on 1080 (default socks port) or set a socks proxy running on 3128 (default http port) easily.

The best way to know the type of proxy is to test it. If a proxy is shown working in Elite Proxy Switcher, it’s a HTTP proxies. If a proxy is shown working in Socks Proxy Checker, it’s a socks proxy.

However it’s a fast way to judge the type of a proxy roughly by its port without testing it.

Google Proxy is Precious

Proxies that support searching on Google are called Google proxy. Many SEO (Search Engine Optimization) programs make large number of queries on Google to get information such as ranks and competitors. They should use a Google proxy to avoid being banned by Google.

Google Verification Page

If your IP is suspect, Google may show a page to verify that you are a human instead of robot. Google allow using proxies as long as you can pass this human verification.

Google Proxy is banned

You can submit the characters in the picture to continue to use Google search. However your SEO program usually can’t do that as you. You can’t use that proxy to search Google in your SEO program. You have to find clean proxies so that Google won’t show that verification page.

How to Check Google Proxy

How to find those clean proxies? The professional edition of Elite Proxy Switcher 1.20 has the feature. It can check whether a proxy supports searching on Google. You can then export the Google proxies into a text file by ctrl+c and ctrl+v so that your SEO program can use them. If you manually use the proxy to search on Google, you need not to test this feature. It’s because you can easily pass the human verification.

Google Blocks Proxy

Some proxies may become Google proxy if someone passes that verification using it. This entitles the proxy to use Google for some time. After a while it needs verification again. It’s why the testing result of some proxy may change from time to time. However not every proxy can become Google proxy. Google blocks some proxies permanently because of the serious abuse. If you are using those proxies on Google, you will see this page.

Google Proxy is permanently banned

Google Proxy is Precious

We tested 2540 proxies. There are only 67 Google proxies among the 718 working proxies. Google proxy is really precious.

Set Proxy for Browsers

Here is a tutorial with pictures showing how to set proxy for your browsers (Internet Explorer, Google Chrome and Mozilla Firefox) step by step. It’s similar to set proxy for other browsers such as safari and opera.

Set Proxy in Internet Explorer (IE)

1) Click the Tools -> Internet Options in Internet Explorer to get to the following screen:

IE Proxy Internet Options

2) Click the Connections tab and then LAN Settings.

IE connections

3) Select Use a proxy server and enter your proxy server IP Address and Port into the field. Click OK and the proxy server is now set. For example, the proxy is 11.22.33.44:8080. You should input it like this.

IE Lan Settings

Set Proxy Server in Chrome

Google Chrome uses the system proxy settings. That is, it uses the same proxy as IE. So you can use the same method as IE to set proxy for Chrome. You can also click the Chrome menu Setting -> Under the Hood -> Network -> Changing proxy settings. It will popup the same proxy setting dialog as IE.

Set Proxy Server in Firefox

1) Click the Tools -> Options in Firefox to get to the following screen:

Firefox Options Dialog

2) Click the Advanced -> Network -> Settings.

Firefox Proxy Options

3) Select Manual proxy configuration and fill in the proxy IP and port. However, it’s a good choice to use system proxy settings in most cases.
