proxy detection is a critical component of a successful online marketing strategy. It can help you keep fraudsters, spammers, and bots at bay. It also allows you to monitor suspicious activity so that you can avoid blocking traffic that isn’t malicious.

Proxies are often used by hackers to hide their IP address, so they can access websites and services anonymously. They can also be used by fraudsters to skew campaign data and defraud advertisers.

Fraudsters typically use proxies to mask their true identity when making fraudulent purchases or chargebacks. This is often accomplished by spoofing the geolocation of their IP address.

Some proxies are harder to detect than others, but there are ways to identify them. For example, a good proxy detector tool will look for any logging information related to the user’s browser.

The Art of Proxy Detection: How to Identify and Avoid Proxies in Your Network

A DNS leak is another indicator that a user is behind a proxy. This occurs when a DNS query is sent to an ISP DNS resolver, but the client uses a VPN or another proxy.

Ping tests are another way to detect a proxy connection. These tests measure the minimum time that a request can take to send the smallest possible amount of data.

In addition, a proxy detector will also check if the client uses a VPN to connect to the Internet. This is important because a VPN can leak your original IP address.

For this reason, it’s important to use a proxy detection service that can provide a variety of metrics to identify a potential fraudster. This can be done by looking at the location of the IP address, a ping test, and the traffic’s headers.
