ISP Proxies vs. Residential Proxies – Ultimate Guide
Enrika Pavlovskytė
Simulating organic, human-like traffic can be a headache, but for some tasks, like account management or web automation, there’s no way to go without it. Both ISP and residential proxies can help, but you can’t just buy and deploy them blindly. You need to learn their strengths, understand their weaknesses, and get crafty when utilizing them.
What are ISP proxies?
ISP proxies are a particularly interesting type of proxy because, being a hybrid of both, they bridge together datacenter and residential proxies. Like the former, ISP proxies are artificially made and hosted on a server. This makes them fast, stable, and consistent.
Moreover, ISP proxies are registered with internet service providers — companies like Spectrum, Xfinity or AT&T that provide access to the internet. Because of that, ISP IPs are perceived as residential and websites are less likely to block them.
What are residential proxies?
Residential proxies are intermediary servers often employed to protect user information when accessing a target site. While this is true with most proxies, residential servers have a nice perk. They will show an IP address of a real internet user who had consented to lend their IP addresses. Because of this, residential proxies are the most difficult type of proxy to detect.
Ethical residential proxies
Unfortunately, some residential proxy providers acquire IP addresses from unconsenting users or, in other words, without their explicit knowledge. This practice is highly unethical, and proxy buyers are advised to look into the origin of a proxy IP address. The best way to go is to use A+ proxies, where the IP owner consents and is compensated.
Are ISP proxies residential?
ISP proxies will only be residential in the eyes of the target website, as they’re likely to perceive both residential and ISP proxy traffic as organic. However, the consensus across the industry is that the two are entirely different. That’s because residential proxy IP addresses belong to real internet users and ISP proxy IP addresses are artificial (hosted in a data center).
On the other hand, you may sometimes see ISP proxies listed as dedicated proxies or residential proxies (static residential proxies, to be precise). That’s to reflect the consumer preference: a proxy identified as residential by websites and also static. Actual residential IP addresses are extremely unstable, meaning they have rotating IP addresses, and it isn’t easy to make them static. ISP proxies is the best way to achieve a residential proxy's anonymity and a datacenter proxy's stability.
ISP proxies: Advantages and disadvantages
Like many other things, ISP proxies have numerous strengths and weaknesses some of which are:
Advantages
High speed and uptime: ISP proxies offer superb speed and uptime as they’re hosted on data centers and have higher bandwidth.
Less likely to get blocked: Associated with internet service providers, these private proxies often appear as organic traffic to websites. As a result, the target website is less likely to block you.
Long sessions: Where residential proxies can be flaky, ISP proxies can maintain long sessions, making them an ideal choice for tasks requiring a stable connection.
Disadvantages
Low subnet diversity: IPs of ISP proxies are grouped in ranges (or subnets). One drawback is that if one IP in the subnet is blocked, others will likely meet the same fate.
Residential proxies: Advantages and disadvantages
Likewise, residential proxies can have both pros and cons:
Advantages
Very difficult to detect: Because these IPs come from real people’s devices, it’s very difficult for websites to identify them as proxies.
Large IP pools: IPs of residential proxies often sprawl across the globe, offering a wide array of location choices with precision targeting.
High IP diversity: It’s extremely rare for residential proxies to come in a subnet. So, if one IP address gets blocked, others will stay functional.
Disadvantages
Unpredictable speed and stability: People’s internet speed and stability vary. So, if you use a residential proxy, its performance can be affected accordingly.
Use cases
It’s not uncommon for residential proxies and ISP proxies to be used for similar purposes. For example, both will be suitable for web scraping, but residential proxies will have an easier time bypassing sophisticated anti-bot systems, while ISP proxies will be handy for websites requiring a consistent IP.
The same goes with other use cases; both proxy types will do the job, but you probably want to choose the one that will excel at it. With that in mind, people tend to choose ISP proxies for:
Account management
Enabling multi-login access at organizations
And residential proxies for:
ISP vs. residential proxy comparison
| Residential Proxies | ISP Proxies | |
| Speed | Medium | High |
| Use cases | Websites with extremely harsh anti-bot measures | Websites that need a consistent IP address |
| Source | Real user devices | Data centers |
| Anonymity | High | Medium |
| Stability | Low-Medium | High |
