What Are Backconnect Proxies? A Practical Guide
Learn about backconnect proxy servers and their uses.
By giving you access to a pool of IP addresses, backconnect proxies simplify proxy management for any large scale project. They also make an inseparable part of rotating proxy networks. This article will teach you more about backconnect proxy servers: their features, working principles, and how they compare to regular proxy lists.

A backconnect proxy is a gateway address that gives you access to a pool of proxy IPs. Instead of receiving a list of IPs directly, you rather connect to a proxy server and it fetches them for you. This extra step makes backconnect proxy servers managed, while regular proxy lists are unmanaged by the provider.
A backconnect proxy address connects you to a proxy provider’s server. The server then selects an IP that meets your requirements from a pool of available proxies. As a result, you can use multiple IPs through one address, without managing them yourself – everything is done in the backend.
Backconnect proxies usually come in the hostname:port format. The hostname looks like a regular URL, for example:
en.proxyprovider.com. It’s effectively an IP address in disguise, to make it more readable.
The port gives the proxy server further instructions. It can be any number depending on the provider’s configuration. The full format would look something like this:
Some providers let you modify the backconnect address to filter IPs based on location or rotation frequency. Proxy providers like Crawlera and Oxylabs outfit their servers with even more advanced features: request throttling, intelligent proxy rotation, and so on.
Due to the logistics involved, most backconnect proxy pools are shared between users. That said, it may be possible for demanding clients to receive dedicated backconnect proxy pools.
- Residential – the classic backconnect proxy type, one you’ll find in marketing pages when Googling the term. And for good reasons: the way residential proxies work, it’s simply unfeasible to provide them in any other format. Residential IPs use devices of real people – with unstable connections and availability – so they need to be able to rotate without changing the proxy address.
- Mobile – many of the mobile proxies come from real users as well, so they follow the same logic as residential proxies. An exception would be providers that have set up their own dedicated phone farms – but even then backconnect servers reign supreme.
- Datacenter – while it’s unusual, datacenter proxies can also be backconnect. Some providers have introduced backconnect shared proxy pools for less experienced users or those targeting unsophisticated websites. Notable examples would be Smartproxy and Luminati.
Let’s see how backconnect proxy servers compare to proxy lists.
So, these were backconnect proxies. With simpler proxy management, better scaling, and value-added features, backconnect proxy servers can be called an evolutionary step over the tired proxy lists. Not quite perfect, but one that was necessary to move the proxy industry forward.
