Often at work, I encounter services that provide offerings such as resident proxies. Yet, I have never delved deeply into the topic. I have always simply consumed the product “as is,” as some lazy authors like to say.

I have a general understanding of how this type of service works at a layman’s level, and I became interested in exploring the topic more deeply and attempting to share the conclusions I reached through a deeper understanding of what resident proxies are. Let’s see what comes out of it. No recommendations here—just the subjective, evaluative opinion of yet another “specialist.”

Proxy servers are intermediaries between your device and the internet, allowing you to hide your real IP address and alter the appearance of your connection. Think of it as a white camouflage coat in snowy weather, if we speak in very simplistic terms. Let’s start from that—options for camouflage. However, comparing with camouflage coats would be rather dull; instead, let’s recall animals and insects that use camouflage and try to draw a parallel. In fact, I’ve already done so.

Introduction to Camouflage – What Are Resident Proxies and Why Are They the Gecko in the World of Proxies, Not the Chameleon?

There are two main types of proxies – server proxies (some even call them data center proxies) and resident proxies. There is also an important subtype – mobile proxies, but I would classify mobile proxies as a separate branch under resident proxies; however, let’s not go into details here. If you want to understand the difference between these types of proxies, I recommend reading the article “Resident, Mobile, or Server Proxies? A Layman’s Perspective.”

If I were to rank the masters of camouflage, I would place the Malagasy flat-tailed gecko in the top spot, followed by the common Yemeni chameleon. Similarly with proxies – resident proxies are the gecko, while server proxies are the Yemeni chameleon.

And as for mobile proxies, I would call them the Orchid Mantis

As I mentioned above, I will not delve further into comparisons; this article is devoted to resident proxies. The key point to understand is that resident proxies use IP addresses belonging to real people, while data center proxies have their own pool of addresses, all located under the same “roof.” And as the picture shows, resident proxies work better in terms of camouflage than server proxies.

Where Do the IP Addresses for Resident Proxies Come From?

Obviously, for a user who wants to use resident proxies, these proxies must have an offering—a pool of IP addresses that the provider can offer to a client under the banner of “resident proxies.” But where do they come from?

So, who is this Robin Hood that takes IP addresses from ordinary people and gives them to the extraordinary? Let’s figure it out.

There are several models by which an ordinary user’s IP address can end up in the pool of IP addresses:

Voluntary Connection of Users to Resident Proxy Networks:
Some proxy providers widely use so-called affiliate programs, whereby a user can earn money from their traffic. The user joins the program, agrees to the proposed terms, and begins sharing their IP address for the provider’s needs, with the provider paying them a certain reward.
In this scheme, everything is completely transparent, but there is a nuance—users from countries with a high standard of living are less likely to participate in such programs.
Affiliate Agreements with Internet Service Providers to Replenish the Pool of Resident Proxies:
Some providers offering resident proxies to clients enter into contracts with local or regional ISPs to gain access to an existing pool of residential IP addresses. In turn, the providers may (or may not) include in their agreements with users a clause stating that their IP addresses can be used by third parties. Naturally, in such a situation, most of the responsibility lies with the provider, but there is an element of ambiguity, isn’t there? You might even now, while reading this article, be sharing your IP address with a resident proxy service through your ISP, while the author of this article uses your IP address for… who knows what.
Aggregation and Leasing of IP Addresses for Resident Proxies:
This method naturally flows from the previous one. There are companies that, upon signing a contract with an ISP, use the acquired addresses themselves, while others collect these addresses and resell them to third-party services (which, for some reasons, cannot obtain them directly).
Using Existing Infrastructure:
This involves utilizing already installed home devices, routers, or IoT devices to form a network of resident proxies. In other words, the proxy provider, acting as the supplier, does not rely on an ISP but on a provider of physical equipment, and conducts all contractual relations directly with them. I must note from the start—I have not found any concrete evidence of this model, but I see no reason why it cannot exist.
Using Applications to Obtain Real Users’ IP Addresses:
In my opinion, this model is the most widely employed in this niche, as its scalability potential far exceeds that of expanding an ISP’s client base. An ISP is limited to a certain region and is constrained by its infrastructure, whereas applications can spread independently of region; they do not require any accompanying infrastructure for someone like John Mulkovich in New York or Peter Czech in Czechia to connect.
What kind of applications are these? I won’t mention specific names, as I do not wish to list them, but suffice it to say—some so-called free services or applications do not offer their services “for free” without reason; some of them stipulate in their agreements that your IP addresses may be used for transfer to third parties.

Decentralized VPN Services – An Alternative to Resident Proxies

Such services can be classified as a separate system, as they use real IP addresses within their ecosystem and do not resell them to third parties (or perhaps they do resell them). However, I consider it necessary to discuss such services within the framework of this article. The essence of decentralized VPN services is that they unite real users into a single network, allowing each participant to use another participant’s IP address. The idea is interesting, but there may be security concerns for individual participants in the chain.

The Principle of How Resident Proxies Work

We have already established that resident proxies use IP addresses that belong to real households; now, let’s delve into how it works under the hood.

Imagine you want to send a letter but do not want the recipient to know your real address. Instead of sending the letter directly, you hand it over to a trusted courier. This courier delivers the letter to the recipient, but on the reverse side of the envelope, the courier’s home address is provided instead of yours. The recipient sees a letter that came from the courier, not from you.

From a technical perspective, using a proxy works on a similar principle. When you make a request through a proxy server:

Step One: Your computer sends a request to the proxy server, just as you hand a letter to a courier.
Step Two: The proxy server receives your request, substitutes your IP address with its own, and then sends the request to the target server. This is akin to a courier forwarding a letter using their address.
Step Three: The target server sends the response back to the proxy server, not directly to you.
Step Four: The proxy server delivers the response to your computer, maintaining the “camouflage” of your real IP.

Thus, thanks to the proxy server, the target server sees the request as coming from it rather than from your device, providing an additional layer of anonymity and helping to bypass geographical or network restrictions.

And the cherry on top: the courier (resident proxies) is a real person, not a postal service (data center proxies). That, in a sense, enhances security.

Possible Drawbacks and Limitations

Like any tool, resident proxies have their nuances:

Cost: They are more expensive compared to server-based solutions.
Speed: In some cases, the speed may be lower due to routing through home networks.
Limited Quantity: It is not always possible to obtain the necessary number of IP addresses for large-scale tasks.

Nevertheless, after having tried resident proxies compared to server proxies, I tend to use this option because they truly work as they should. If I need to evaluate search engine results in a specific region, I always use them, as these proxies provide the assurance that my browser won’t reveal my real IP address. Admittedly, the price can indeed be a problem—they are significantly more expensive. But the quality is worth it.
