Each technology has its advantages and disadvantages. Now we will try to figure out what are the advantages of backconnect proxies over regular proxies, as well as what are the disadvantages.
We are used to that IPv4 proxies are IP: port addresses. For HTTP/S, the standard ports are :3128 :8080 . For socks5 proxy — :8085 :5000
The basic principle of backconnect proxies is that they act as an intermediary between the actual proxies and the client. That is, when you request a backconnect proxy, your outgoing IP will be completely different. This means you don’t have to worry if you have 100 identical IPs to work with a backconnect proxy, it doesn’t matter much.
Benefits of a backconnect proxy:
Since backconnect proxies are a kind of additional «layer» between the actual proxies, we can talk about the high level of reliability of such proxies. In addition, backconnect proxies can be with rotation (backconnect rotation proxy) or without rotation (backconnect static proxy). In the case of a proxy with rotation, this gives a huge advantage to the client, since using the same set of proxy addresses, the client will receive all the available proxies that are located behind these addresses. Thus, if we talk about backconnect proxies, we can say that you «filled them once and forgot about them.»
To sum up the benefits:
— Stability of work
— Possibility of automatic rotation without changing the addresses of use
— Possibility of balancing or special work algorithms (useful if the resource you are working with requires special conditions from the proxy)
Disadvantages of backconnect proxies:
Unfortunately, there are also disadvantages. One of the important and perhaps the most noticeable drawbacks is that backconnect proxies usually use sets of duplicate addresses for their work. This means that when working with a backconnect proxy, you may have a situation where your hoster or home provider decides that you are conducting a dos attack on a third-party IP address.
Unlike working with backconnect proxies, classic ones do not have such a disadvantage, since usually, each proxy has a separate, unique IP.
In addition, as mentioned earlier, a backconnect proxy is an additional “layer” between you and the proxy. This layer adds time to process requests. As a result, the «ping» increases. But usually, the increase is not 0.1-0.3 seconds, which is generally tolerable.
To sum up the disadvantages:
— The same IP port connection addresses of the proxy (the hoster may regard it as a dos attack)
— Ping can be higher than classic proxies
