Proxies have become indispensable tools for various online activities. Once you've acquired a proxy, it's crucial to evaluate its performance using reputable tools or IP-checking websites. Numerous free platforms are available for this purpose, including Whoer, IPFighter, Whatismyip, Browserleaks, and f.vision.

Here's a breakdown of these trustworthy websites for assessing proxy performance:

Whoer is a widely recognized platform frequently used for IP checking. It offers a detailed examination of various IP-related aspects, including ISP, DNS, location, time, proxy usage, and blacklist status. This comprehensive analysis makes it a go-to choice for users keen on understanding the nuances of their proxy performance.

IPFighter is a reliable platform for testing IPs and browser fingerprints. The site assigns a score out of 100, offering specific information about the IP, including blacklisting on certain websites, WebRTC or DNS leaks, time and language inconsistencies. It also provides solutions for identified issues.

Whatismyip is a versatile website allowing users to check IP information, DNS details, IP registrant details, and even test the upload and download speeds of the IP. The IP WHOIS Lookup section enables users to delve into registration details, offering a comprehensive overview of the proxy's performance.

Browserleaks is a reputable platform renowned for its in-depth evaluations of both browser fingerprints and IPs. It includes an integrated IP location map for easy reference, simplifying the process of verifying location information. Users can also inspect for DNS leaks, ensuring a thorough examination aligning location details with the IP address.

Similar to Browserleaks, f.vision serves as a valuable tool for verifying IP and browser fingerprint information. Notably, it goes the extra mile by providing an extensive list of websites that have blacklisted the IP, akin to the comprehensive insights offered by IPFighter. This additional layer of information aids users in gauging the proxy's standing across various platforms.

When assessing IP quality, it is advisable to cross-reference results across multiple websites rather than relying on a single source. Platforms like IPFighter, which offer IP scoring, prioritize issues such as blacklisting or WebRTC leaks, resulting in more significant point deductions compared to other concerns. This comprehensive approach ensures a thorough evaluation of proxy performance.
