Proxy types by protocol
Depending on the protocol used by the proxy, it can be HTTP, HTTPS or SOCKS.
An HTTP proxy is any proxy that applies the Hypertext Transfer Protocol (HTTP) to communicate with a web server and a client (browser). Due to the extensive usage of HTTP on the Internet, the majority of proxies are HTTP proxies.
Such proxies are able to get through to web pages, and even though they can still reach web sites with secure HTTPS, this protection would be lost in the process of usage.
Since HTTP connections operate simpler than the SOCKS protocol, bots and parsers perform much better with HTTP proxies.
HTTPS and SSL Proxies
SSL(HTTPS)-proxies operate with SSL (or Secure Socket Layer), an extra level of security applied to HTTP to keep its data protected. It appears to have security certificates which are used to encrypt traffic end-to-end and keep data from getting intercepted during transfer.
A proxy that maintains SSL creates a secure connection to the client and to the web server to prevent anything external from intruding. The HTTPS proxy keeps you protected when performing operations or accessing web sites with your login name and password.
A SOCKS proxy establishes a TCP connection to route traffic on the client’s behalf. It is a technique of tunneling through firewalls, and in this setting even the proxy itself is not able to capture the data, so SOCKS proxies are primarily handled by applications. Therefore, SOCKS is far more reliable than the HTTP proxy.
But SOCKS5 proxies contain even more sophisticated functions to provide connection security. The only downside is that certain bots do not accept SOCKS, so you have to check that your bots can handle this protocol.
Proxy Types by Anonymity Level
Transparent proxies are also referred to as intercepting proxies, embedded proxies, or forced proxies. These proxies do not change queries or replies, so anonymity is not changed and websites can receive your IP address. Transparent proxies are commonly seen on community Wi-Fi grids, and are generally seen to give permission only to those who have permission to access them. A lot of servers also utilize transparent proxies to provide cached content for quicker deliveries.
Anonymous proxy servers modify the HTTP header, substituting your IP address for theirs, and include extra redirection commands so that the web server does not find out your IP address. Websites can detect that a proxy is in use, but cannot identify the real address. These types of proxies ensure the lowest level of anonymity and can operate with all protocols.
Elite Anonymous Proxies
Elite anonymous proxies are the same as anonymous proxies, but they are a lot more secure because they offer the greatest level of protection available. The proxy modifies the HTTP header to totally delete any details about you, and does not include any redirection commands. This way, the site does not detect the request for a connection from the proxy and considers it to be any normal user connection.
Elite anonymous proxies are very valuable if you run bots for parsing – with them, the web server won’t recognize a proxy you run, and your IP won’t be blocked.
Types of proxies by location
Proxies in Data Centers (DPC)
These proxies are placed on servers designed for their work. Such servers operate with high-speed connections and dedicated software to help maximize productivity. This leads to proxies that have fast speeds, lower pings and can offer elite anonymity. Data center proxies are appropriate for most business applications, particularly for bots.
But they demand that the seller has a data center in each of the locations where it wishes to offer its IP addresses, and data center locations are fairly restricted. The overall amount of proxies that the seller possesses is also restricted to a couple of thousand. Thus, proxies on servers in data centers are simpler and blocked merely by subnet mask.
Resident proxies make use of the computers of actual humans and their connections in their proper homes, which are given by real ISPs. A resident proxy seller doesn’t really have ownership of these servers, but instead simply “rents” them in return for services such as a VPN, for instance.
This enables sellers to have a massive residential pool of proxies from practically all over the globe. These proxies are comparatively less slow than data center proxies, but they are appropriate for a lot of business applications because of their variety.
Proxies by type of use
Open proxies are public proxies that do not need any authentication technique when connecting. But because they are freeware and publicly available, in most instances these proxies do not work well or at all and are not secure, so they can be configured by hackers to steal data.
Open proxies are also commonly referred to as public proxies, but we do not advise you to operate them.
Closed proxies (private)
Closed proxies are proxies that are secured by different authentication techniques to stop any unauthorized use by unauthorized individuals. Closed proxies are traded by a lot of businesses. Closed proxies are of two kinds, according to the amount of people they handle.
Dedicated (private) proxies
Dedicated proxies (also known as private proxies) work for you alone and access is confidential. Private proxies offer better productivity and protection, but are slightly more expensive than shared proxies. Proxies that focus on ticketing, parsing, and purchasing unique sneakers are practically always private proxies because they demand high productivity, and sharing proxies with other people raises the likelihood of receiving a ban.
Shared (shared) proxies
These proxies share their assets among 2-5 users. Every single user can work simultaneously with all others, so the bandwidth is split equally between everyone. The drawback of using shared proxies is that they offer much slower speeds due to shared access, and they can be shut down because of other users. But shared proxies are generally available for a much cheaper price than private dedicated proxies.
Web proxy refers to the creation of a proxy server on a site. This proxy doesn’t have to be configured in an application, like a browser or bot, to normally access the information. This type of proxy is a website with a one line string with the help of which you can get access to the site you want and mask your IP address as well.
CGI Web Proxies
These proxies are managed through a web interface referred to as the Common Gateway Interface. You can enter the requested URL to access the page on the site. There are just a number of CGI web proxies that are operated by thousands of sites.
The data you enter when using these proxies is all run through the owner’s site, and he can simply access all the data if he wishes. Therefore, no sensitive data needs to be involved in these proxies. These proxies also are not configurable for use in a different software, which turns them out to be unusable for the majority of business purposes.
Types of proxies by IP address
The majority of proxy providers in data centers assign a specific amount of servers to a customer for a specified cost, and the charge rises as the amount of proxies grows. These proxies are allocated to a particular user and can be operated one at a time.
If a proxy becomes blocked, the dealer normally suggests a different proxy every other month. Beyond that, the customer cannot replace them.
Rotational (rotating) or reconnection proxies
Backconnect proxies, otherwise called rotating proxies, automatically replace themselves over a period of time. This makes it possible to send a new IP address for every query, which results in much better anonymity, higher speeds and no blocks.
Backconnect proxies are excellent for parsing. They typically comprise of resident servers ( due to the great amount of connections needed), but certain providers in the data center are exploring rotating proxies as well.
Types of proxies by data change
Forward (direct) proxies are ordinary proxies used when you reach web material anonymously. This type of proxy is usable by clients (browsers) for anonymity. They accept a query from a client, forward it to a web server for treatment, and then forward the answer from the server to the client. In fact, all the kinds of proxies we analyzed earlier are direct proxies.
A reverse (reverse) proxy typically operates on the web server side to handle traffic, verify or decrypt connection requests, or just cache data for quicker deliverability. Reverse proxies are not normally used by ordinary individuals to ensure anonymity. Rather, they assist the web server to stay secure from attack. Reverse proxies can also spread traffic over multiple servers to perform load balancing.
Proxy types by IP reuse
Proxies that have not been reused are referred to as primary or unused proxies. Primary proxies are usually not straight up just established and with a new IP address, but they haven’t yet been used to operate on specific websites. This is the reason why a lot of proxy sellers prevent access to sites other than the one you specified.
Used or oversold proxies
While not clearly stated, the majority of proxies have been previously tried in one way or another. Because Web sites unban addresses after a specific amount of time, it is quite possible to use these proxies after a certain amount of time when the site ( supposedly) unbans them.
