Online Proxy Checker
Test proxy speed, protocol type, exit IP, and geographic location. Supports HTTP, HTTPS, SOCKS4, and SOCKS5 with bulk testing up to 10 proxies at once.
Try it freeIP Address Checker
See your current public IP address, ISP, and approximate location. Useful for verifying that your proxy or VPN connection is active and routing correctly.
Try it freeIPv6 Compatibility Checker
Test whether any domain supports IPv6 by querying its DNS AAAA records. Check IPv6 readiness before deploying IPv6 proxies on a target site.

Proxy tools help you verify that your proxy setup works correctly before running production workflows. Testing proxies upfront saves time and prevents failed requests, blocked connections, and inaccurate data collection.
Verify Proxy Anonymity
Confirm that your proxy hides your real IP address. The IP checker shows exactly what websites see when you connect through a proxy, so you can verify your identity stays protected.
Check Geo-Targeting Accuracy
Verify that your proxy exits from the correct country and city. This matters for price monitoring, localized content testing, and any task where geographic location affects the results.
Test Before You Deploy
Catch dead proxies, wrong protocols, and slow connections before they affect your workflow. Bulk testing lets you validate an entire proxy list in minutes instead of discovering problems mid-task.
What Each Tool Does
Proxy Checker
Paste a list of proxies and test them all at once. The checker sends a request through each proxy, reports whether it responds, identifies the protocol (HTTP, HTTPS, SOCKS4, SOCKS5), and shows the exit IP with its geographic location. Supports authenticated proxies with username and password. Tests up to 10 proxies concurrently for faster results.
Open Proxy CheckerIP Address Checker
Instantly see your current public IP address along with your ISP, city, country, and timezone. Supports both IPv4 and IPv6 with automatic detection. Use it to verify that your proxy or VPN is active and routing through the correct location.
Check Your IPIPv6 Compatibility Checker
Enter any domain to check if it supports IPv6 connections. The tool queries DNS AAAA records and displays all IPv6 addresses found. Essential for planning IPv6 proxy deployments, since your target site needs IPv6 support for IPv6 proxies to work.

Frequently Asked Questions
Start with the IP address checker to see what websites currently see when you connect. Then use the proxy checker to validate any proxy lists before you run them in production. If you plan to deploy IPv6 proxies, use the IPv6 compatibility checker on your target domain first to confirm it supports IPv6 connections.
No. All three tools are open to anyone. There is no signup, no login, no credit card, and no email capture. Open the tool, run your test, close the tab.
Yes. Each tool has its own permanent URL. The proxy checker also accepts a proxy via the ?proxy= query parameter, which is useful for sharing a pre-filled test link with a teammate. Results themselves are not saved on our servers, so shared links re-run the check.
Yes. All three tools are fully responsive and run in any modern mobile browser, including Chrome for Android and Safari on iOS. The same features available on desktop work on mobile with no reduced functionality.
No. The tools are diagnostics that run against proxies and domains you provide. They do not give you access to ColdProxy's proxy pool. To test ColdProxy proxies on your own targets, our hourly plans serve as a low-cost real-world trial — see the pricing page for details.
Yes. The IP checker auto-detects and displays either address family. The proxy checker works with IPv4 and IPv6 proxy endpoints, including SOCKS5 over IPv6. The IPv6 compatibility checker is purpose-built for IPv6 and returns every AAAA record it finds.
Yes. You can run the tools as part of any commercial workflow, include screenshots of results in client deliverables, or reference the tool URL in documentation. We only ask that you do not scrape or resell the tool output as a competing service.
