Before we get into the nitty-gritty of what resident and server proxies are and how to use them, we must first understand why proxy servers are necessary when processing a large amount of data.
It’s simple to be fooled: “I can get 1,000,000 pages a day if I can just manage 10-100 pages each day… You only need to increase the capacity…” Unfortunately, it will be tough to scale the activity in such a way that you can get a little bit of data from the Internet, and there are numerous methods that can assist you with this. But it is a far different scenario to receive a huge amount of data on a daily basis; this is a difficult job due to the many variables:
- stability of work;
- infrastructure capacity;
- regular code support;
- data quality control and others.
In fact, web data extraction consists of three components:
- The parser program (or the so-called spider);
- Proxy server;
- Source (Sites and applications).
Currently, websites have a variety of technologies at the IP and browser level to defend against intruders. Geofences, TCP/IP fingerprints, browser fingerprints, and so on are all examples of this. The need to scale data extraction from the network implies that you will require a technological level capable of handling a large amount of data on a regular basis. And, at the very least, it will allow you access to information since, for example, if you reside in Russia and the target site shows information only available to visitors living in the United States.
Are there different types of proxies? Server proxies (Proxy Data Center), resident proxies (private or home), IPv4/IPv6, Sock4, Sock5, Sock5s …
Yes, there are various kinds of proxy servers. In reality, the selection of a proxy depends on what data you need to gather and where you want to collect it. A certain type of proxy or a combination of them will be appropriate for you depending on your requirements.
A proxy or proxy server is a computer that sits between you and the website you want to visit, serving as a go-between. It serves as a link between your local network and a large-scale network, such as the Internet. The proxy server, on the other hand, is a middleman, monitoring connections between the sender and receiver. All incoming data is sent through one port and redirected to the rest of the network via another.
Proxy servers are used to hide the server’s actual IP address from which you’re requesting data and to redirect traffic. They also employ caching technologies that keep requested resources on the server in order to increase performance. They can encrypt your data, thereby making them unreadable during transmission and, for example, blocking or allowing access to specific sections of a website depending on the IP address.
IP addresses that impersonate your own IP and are used to view blocked sites and obtain material without restriction. These proxies can be resident or mobile, which replace your real IP address with one from their list. You may use any of these proxy types to surf anonymously and change your desired region. However, all of these proxy sorts are distinct, and they differ in terms of price, performance, and performance. So, if you want to parse data on a huge scale and frequently, which type of proxy should you utilize?
Server proxies or Data Center proxies are fast, affordable, but without any special advantages and are easier to block
IP addresses hosted in data center operators’ infrastructures are known as data center proxies. They exist in a variety of forms:
Public – a typical free proxy. These are IP addresses that you can find on the internet for free, but they are of no value for large-scale data collection projects because they are quickly blocked by many users. Keep in mind that because they are openly accessible, they represent a security hazard since you can’t be sure whether your data is intercepted along the way.
Shared IP addresses are IP addresses that may be used simultaneously by many people. For simple, non-time-consuming data analysis, this is the ideal solution. Proxies might be limited because they can be used by many individuals, and recurring requests are a common source of abuse. Blocking may become critical in certain situations until you utilize proxy management logic to keep an eye on the health of IP addresses, which includes IP address rotation, request limiting, and more.
Private – the IP addresses of the servers that you own alone during the entire rental period.
Dedicated – addresses to which you have acquired the rights to use this IP from a data center provider (for example AWS, Azure, Equinix, Digital Realty, etc.), or if you actually own the infrastructure yourself.
Pricing of server proxies
There are several ways to charge for server proxies, with the most popular being that of paying for each IP address on a monthly basis. Another method is to pay for traffic that transmits through an IP address. There’s a model for when payment is given following the completion of a successful request. Depending on the specifics of the job, you’ll need to choose one or the other.
Advantages of server proxies
Fast and stable – Server proxies in cloud environments are different from their counterparts on-premise since they operate within an enterprise-grade infrastructure. Server proxies of this sort are a dependable tool for parsing sites, especially when they are used with some sophisticated logic to get the most out of them.
Shared or private – Now, you can use public proxy servers that others are using to save money, or purchase a proxy for personal usage. This prevents anyone from misusing the IP address.
Affordable – Typically, a proxy for a private data center is not very expensive. This makes the proxy accessible, albeit at the expense of sharing costs with other customers. You get what you pay for.
Unlimited traffic. Not the amount of data sent, but rather the IP address is factored into the costs. This is a wonderful alternative if you’re receiving huge quantities and aren’t in a rush.
Disadvantages of server proxies
There are only a few places where you can establish IP nodes, and they all need a “full” infrastructure, which implies a physical presence. As you might have guessed, establishing your own servers in various locations and not just renting consumes a significant amount of money. However, it may be tough to locate a data center firm with global coverage. You must look for a provider that maintains a pool of IP addresses and purchases them from several sources across the world to ensure there are no restrictions on where you can operate your business.
It is easy to detect – A private ASN is never assigned to a public IP address, and the subnetwork is likely to be quite restricted in variety. As a consequence, even if you use a proxy that is completely anonymous, the target sites will realize you are using one. This might or may not be an issue, depending on the target domain you wish to extract information from. In order to fully take advantage of IP addresses for enterprise-level parsing and reap the benefits of their shared, lower total cost of ownership, you must use your own tools to avoid this frequent blunder.
Inconvenient to use –To use a typical server proxy provider’s client, you must download a text file that contains the IP addresses of all purchased nodes. To put it another way, using one is a pain. It’s difficult to get the most out of them if you don’t spend enough time managing proxies, let alone understanding how to extract data effectively.
Resident proxies are the best of the best, but not for the price
Resident proxies (also called home proxies) – these are IP addresses borrowed from real users: their laptops, phones, and other devices connected to Wi-Fi.
A proxy may be used to hide the true origin of a web page from target sites. This makes it more difficult for target sites to detect them since, for a site, a parser that visits a page via such a proxy appears to be a genuine user, and proxies with this feature also allow users greater choice in terms of geographical location and more precise
Pricing of resident proxies
The costs include the cost of each page view, as well as a few other things. It might be priced separately or added to your monthly charge.
Advantages of resident proxies
High anonymity – Because proxies connect to a real device, resident proxies are tough to differentiate from regular users. Sites generally give them the opportunity to work, even if the user engages in suspicious behavior comparable to that of bots.
A large pool of proxy addresses – The IP addresses for a lot of smaller suppliers have millions of unique combinations, so you can make hundreds of thousands of queries without repeating the same address twice. This provides two more benefits:
A lot of locations – Proxies are also known as “masked” IP addresses because they conceal the actual IP address. These IP addresses are typically located all over the world. There are several leading nations that have a monopoly, but proxies can be found in any remote region.
A wide variety of subnets – One of the most significant benefits is that private IP addresses are rarely assigned to a single subnet. You won’t have to worry about accidentally blocking multiple IP addresses at the same time since this way
Ease of management – Internal servers with reverse connections are used by resident proxy servers. You’re given a URL-like address that connects you to a proxy server, and the server chooses an IP address from the pool provided by the proxy provider. After a few months, the IP address will change, but your server’s address will not. This is really useful for parsing websites because it allows you to keep track of changes to your site without having to start from scratch every time.
IP Address Rotation – Reverse connection servers also allow you to switch IP addresses at the press of a button. Simply choose the switching rate, and the provider will change addresses on your command.
Disadvantages of resident proxies
Potentially slower than server-based – Add an extra link in the connection chain, which is the endpoint (the actual computer or another device) with proxy servers. Finally, because many end users may lack a strong connection to the internet, you can’t be sure whether they have one. In most cases, these proxies are slower than server proxy IP addresses (data centers) due to all other factors being equal.
The connection may be unstable –The service will automatically terminate if the user disconnects, and your connection will be lost. Even if the provider allows you to keep the same IP address for 10 or even 30 minutes, it cannot ensure that you will be able to use it.
Only shared IP addresses – Reverse-connected servers provide access to the same pool, so you’ll have to share IP addresses with other people.
They are much more expensive – Because server proxies are simpler to get and maintain than private (resident) IP addresses, they are more costly. They also have a different pricing strategy from data center proxy servers: the cost is based on the amount of traffic rather than a separate IP address.
Where and which proxies to use?
In practice, resident proxies are more effective at obtaining data from websites with the stringent bot and task restrictions that require geolocation-specific IP addresses. Using these proxies on large businesses, aggregators, and others were gaining access to data is more difficult and content may be dynamic depending on the location (at the country, city, or street level).
The bottom line is that there is no such thing as the “correct” proxy. It all depends on your requirements, the data you want to receive from specific targets sites /domains, and, of course, your budget. The same level of access to sophisticated sites may be available through a pool of server proxies with a sufficient number and sophisticated proxy management logic but at a lower cost. However, in some situations, it is necessary to utilize a proxy geographically at the site of data gathering, and if the acquired data is critical enough, your decision will be resident proxies.
