What Are the Main Features of ISP Proxies?

Using a proxy server is one of the most common best practices for scraping website data or managing multiple social media accounts without being identified as a bot and blocked. And ISP (Internet Service Provider) proxies are one of the most popular proxy types available in the market.

ISP proxies are valued for their fast speed, high uptime and enhanced anonymity. But those are not the only benefits ISP proxies can provide.

This article explains the fundamentals of ISP proxies and their main features so you can get started browsing the internet even safer and execute various tasks faster.

What Are ISP Proxies?

ISP proxies are intermediary IPs associated with an internet service provider (ISP). In other words, they are hosted on a server, not a residential device like a personal computer or mobile phone, and do not include end users.

ISP proxies are valued between experienced proxy users as they combine the functionality of both datacenter and residential proxies. While residential proxies or datacenter proxies might have major drawbacks when running a web scraping bot or conducting market research, ISP proxies are the golden middle when you need a fast yet secure and anonymous connection to the internet.

How Do ISP Proxies Work?

ISP proxies send users’ connection requests via different IP addresses. They hide users’ IP and location before opening the target page, so the websites see the user and their automation software as another person and identify them as a unique visitor.

Datacenter IPs are cheap and fast. However, with the advanced bot detection technologies that most websites employ, they don’t take long to be identified. There is a choice human-like browsing choice — residential IPs. Still, they are expensive and providers often charge by traffic, thus inflating the price even more. And that’s where the ISP proxy steps in.

ISP proxies use ASNs (Autonomous System Numbers) of consumer ISPs and exchange the information with other internet service providers, eliminating the need to deal with unstable Wi-Fi connections and blocked IP addresses.

What Are The Differences Between ISP Proxies, Residential Proxies, and Datacenter Proxies?

For users who are only getting started on their journey with proxies, it might seem that all three available types are pretty similar. However, when diving deeper into the analysis, there are some differences and drawbacks that every beginner and experienced proxy user should be aware of.

  • Anonymity level — residential and ISP proxies, unlike datacenter proxies, assign real IP addresses to users to send scraping requests. That’s why getting your IP blocked or blacklisted by websites with residential and ISP proxies compared to data center proxies is way harder, as the websites identify you as a genuine visitor. Datacenters’ IP addresses are created and controlled by data centers to disguise the actual IP address.
  • Price range — due to the functionality and level of anonymity, residential and ISP proxies are more expensive than datacenter proxies. However, most experienced proxy users recommend getting an ISP proxy as it is a more reliable way of staying safe and sound while browsing and performing various automation tasks.
  • Speed. Although datacenter proxy takes the win when you need to complete specific tasks faster, they are not as reliable as ISP proxies. The same goes for residential proxies, as they are real devices that might get turned off.

The Main Features of ISP Proxies

As we have covered the main differences between residential, datacenter and ISP proxies, we are down to the main features for which ISPs are best known. These proxies carry a list of benefits that help run automated tasks without worry. Here are the main ones:

  • High uptime — as the ISP proxy is run directly by the provider, it is an excellent choice when searching for a steady and reliable masked connection.
  • Static vetted IPs. Most ISP proxies providers offer a pool of carefully selected IP addresses that are not compromised and guarantee top-notch performance.
  • High anonymity. ISP proxies are a safe choice when running various automation tasks, as even cutting-edge technologies fail to identify the bot behind an ISP proxy.
  • Unlimited bandwidth. Most providers offer pricing plans with a certain number of IP addresses and don’t limit the bandwidth.
  • Fast speed. Unlike unstable residential connections, ISP proxies are blazingly fast, ensuring a low response time that scarcely impacts user connection speed. 

What Needs to Be Considered Before Getting an ISP Proxy?

Just like residential or datacenter proxies, ISP proxies also come with their cons. Here are a few downsides of the ISP proxies you need to consider before getting one:

  • Limited locations — like datacenter proxies, ISP proxies addresses are held in servers worldwide. However, the costs and operational struggles make renting multiple servers a great challenge. So, in most cases, ISP proxies are limited to only a few locations.
  • Higher price range is likely the most common downside of the ISP proxies. Mostly because of their sourcing challenges, they are a few bucks more expensive than residential or datacenter proxies.
  • Fewer subnets. Proxy providers rent static residential proxies from various ISPs that fall into neatly related ranges called subnets. While static IPs can have many subnets, they probably will never be able to meet the number of subnets from peer-to-peer residential proxies.
  • Regional ISPs. Lastly, when ISPs rent out their addresses, IP databases may identify these proxies as datacenter addresses, negating their primary benefit, anonymity. However, this issue is mainly associated with small providers that do not have a dedicated infrastructure, and often they provide this information in their FAQ or support page.

Still, the ISP proxies providers constantly work on improving their infrastructure, minimizing the errors users might encounter when using this type of proxy. Some cons might make you doubt the effectiveness of ISP proxies, but they are a reliable choice when searching for a high uptime rate and anonymity level.

Bottom Line

ISP proxies are a powerful combination of datacenter and residential IPs, minus the unwanted speed limitations and error messages. That’s why ISP proxies are becoming a popular proxy choice between researchers, social media managers, and other professionals working with various automation tools.

Although understanding the proxies might look like rocket science at first, they are true time savers once set up. ISP proxies hit all the right notes for security, speed, uptime, and overall performance, and they are worth every penny once you gain the ground experience.
