Static Residential Proxies, also known as ISP Proxies, are a hybrid proxy type that combines residential ISP authenticity with datacenter-level performance.
These proxies use IP addresses allocated by residential Internet Service Providers such as AT&T, Comcast, Sprint, RCN, and Cox Communications. However, unlike rotating residential proxies that route through home devices, Static Residential proxies are hosted on high-performance servers.
What does this hybrid setup mean for you?
You get the best of both worlds: the legitimacy of a residential ISP's ASN (Autonomous System Number) paired with the speed, stability, and reliability of datacenter infrastructure. This is why Static Residential proxies can deliver 300-400 Mbps speeds while still showing a residential ISP to target websites.
These proxies are static by default, meaning they keep the same IP address for as long as you need. If you ever want to change an IP, for a wrong location, a high fraud score, or any other reason, you have options:
Add Auto-Refresh to your plan for automatic IP changes.
Use the Replace Proxies feature to get new IPs on demand.
Why might a checker tool show "datacenter"?
This is the most common question we get, so it's worth explaining clearly.
An ISP proxy lives in two worlds at once: the IP address belongs to a residential ISP, but the server it runs on sits in a datacenter. Different checker tools look at different things, so they can disagree:
Tools that check the ASN (the part that matters most to target websites) will correctly show a residential ISP like AT&T or Comcast.
Tools that check the hosting environment may label the IP as "datacenter" or "hosting", because, technically, that's where the server is.
Both results are expected, and neither means your proxy is faulty. What really matters is whether the website you're trying to reach accepts the connection. The best way to confirm your proxy is working is to test it against your target website and see whether it gets blocked, not to rely on the label a generic IP checker assigns.
Why might the location look wrong?
Some customers notice that a proxy shows a different country or city than the one they selected. This is almost always down to how IP-location databases work.
Location checkers each use their own database, and these databases update at different times. A newly assigned IP can take a while to appear in the correct location everywhere.
We show a Country Confidence level so you can see how reliably an IP maps to its country. Higher confidence means the major databases agree.
If an IP consistently shows the wrong location, you can replace it to get one that maps correctly.
So a one-off mismatch on a single checker is usually a database lag, not a problem with the proxy.
What about a high fraud or IP reputation score?
Fraud-score and IP-reputation tools assign a number based on their own private rules, and those scores can change day to day. A higher score doesn't automatically mean an IP is "bad" or unusable.
These scores are estimates from third-party tools, not a verdict from the website you're trying to reach.
The same IP can score differently across different tools.
If a low fraud score is important for your use case, you can enable our High IP Reputation feature, which gives every proxy in your plan a 0% fraud score, so there's no need to swap IPs to find a clean one. See Understanding High IP Reputation Score for what these scores mean and how to add the feature to your plan.
Understanding ASN and detection
The ASN is a unique identifier for an Internet Service Provider. When websites evaluate incoming traffic, they primarily check the ASN to decide whether an IP belongs to a residential ISP or a datacenter provider.
With our Static Residential Proxies:
The ASN will show a residential ISP (e.g., AT&T, Comcast, Cogent).
The ASN stays consistent across all websites.
Some IP checker tools may still classify the hosting environment as "datacenter", see the section above for why that's expected.
