List of recent proxy IP addresses

List of the latest proxy IP addresses used by bots. You can also access this data through this API. Proxy IPs are often used by bots to conduct different kinds of attacks, such as credential stuffing (stealing user accounts), fake account creation, spamming, and DDoS.

• The list is updated every 6 hours;
• It contains only curated proxy IPs, i.e all the IPs in the list have been verified (I've been able to route traffic through these proxies)
• It IS NOT an aggregation of existing proxy/abuse IP lists;
• It DOES NOT use any data coming from the different bot detection tests and fingerprint tests of this website.

Common questions related to proxies

How to detect if an IP address is using a proxy?

While certain free proxies expose their presence in the X-Forwarded-For header, most proxies used by bots can't be detected as easily. You can use non-deterministic approaches that rely on the connection timing and latency, as well as approaches that rely on the mismatch between the user-claimed user location and other information collected in JavaScript like the timezone and the preferred languages. However, none of these approaches are 100% correct and may also catch legitimate users behind a VPN. Another approach is to use database of proxy IPs, such as the one below.

Is it safe to block proxy IPs?

Not always. Most IP addresses are shared by different users. For example, there might be thousands of users/devices behind the same 4G/5G mobile IPs. It's the same for corporate and university networks that may be used by a lot of users at the same time. Thus, while it's safe to block data center proxy and ISP IPs, you should be more careful with residential IPs since they are located on human user devices. However, knowing that an IP was recently used as a proxy is still a valuable piece of information when it comes to bot detection, fraud detection, and threat intelligence.

What types of proxies are included in the list?

Our IP proxy list contains all kinds of proxies, from data center, residential, mobile,and ISP proxies (registered under the name of an ISP like Comcast, but located in a data center). It also contains free proxies, but only verified proxies through which we have been able to route traffic.

How many proxy IPs are in the list?

As of today, the list contains more than 100K verified proxy IP addresses. The list is growing every day, and I plan to add more data sources to increase the diversity. You can get access to 1,000 IPs on this page or through this API. If you create a free account, you can get access to 5x more proxy IPs.
