Proxy Checker

Use this proxy checker to verify your proxy IP, latency, country, and ASN before using it in production. A reliable proxy tester helps you avoid bad IPs and plan proxy rotation for web scraping.

How to use

Enter your proxy address (e.g. host:port or user:pass@host:port).
Select protocol: HTTP, HTTPS, or SOCKS5 if supported.
Click Check. Results show: visible IP, response time, country, and ASN.

Why check proxies?

Confirm the proxy works before scraping.
See which country and network the IP belongs to.
Measure latency to choose the right best proxies for web scraping.

What the results mean

Visible IP — The exit IP the target site sees. For rotating proxies, run the checker a few times to confirm IPs change if you expect rotation.
Latency — Round-trip time to our test endpoint. Use it to compare regions or providers; lower latency often means faster page loads when scraping.
Country / ASN — Confirms geo-targeting. If you requested a specific country, the result should match; otherwise you may need to adjust proxy parameters or provider settings.

Best practices

Check before production — Validate each new proxy config (host, port, auth) so you don’t waste crawl budget on dead or misconfigured IPs.
Test rotation — For rotating residential proxies, run multiple checks and confirm the IP (and optionally country) changes when expected. See How Proxy Rotation Works and Proxy Rotation Strategies.
Combine with a scraping test — After the proxy checks out, use our Scraping Test to hit a real target URL and see if you get blocked or challenged.

Interpreting ASN and country

ASN (Autonomous System Number) identifies the network that owns the IP. Residential IPs usually belong to consumer ISPs (e.g. Comcast, Deutsche Telekom). If you see a datacenter or cloud ASN (e.g. AWS, DigitalOcean), your “residential” proxy may be misconfigured or the provider may be mixing in non-residential IPs. Use the checker repeatedly with rotating proxies to spot patterns. Best Proxies for Web Scraping and Datacenter vs Residential Proxies help you choose and validate.

Checklist before going to production

Run the Proxy Checker for each proxy config (different regions or gateways).
Note latency and country; ensure they match your expectations and target requirements.
Use Scraping Test with that proxy against a sample of your target URLs.
If results are good, integrate the same proxy into your scraper and monitor success rate and blocks. Proxy Management for Large Scrapers has more on monitoring.

FAQ

Why does my proxy show a different country than I requested? Some gateways require a parameter (e.g. country code in the username or URL path). Check your provider’s docs. If you use our Residential Proxies, geo is set via the gateway or dashboard.

The checker says “Connection failed.” What should I do? Verify host, port, and credentials. Ensure your network allows outbound connections to the proxy. Try without auth first if the provider supports it. Common Proxy Mistakes in Scraping lists other causes.

Should I check every proxy before each run? For a small pool, a quick check is reasonable. For large rotating pools, spot-check a sample and rely on monitoring and retries in production. How Many Proxies You Need for Scraping and Proxy Pools for Web Scraping help size and manage pools.

Before you run a big scrape

Check every proxy config (gateway, auth, region) with this tool. Note the exit IP and country.
For rotating proxies, run the checker 5–10 times and confirm IPs (and optionally countries) change as expected.
Use Scraping Test with the same proxy against 2–3 real target URLs. If you get 200 and real content, you’re good to integrate.
In production, log failures and retry with a different proxy or back off. Proxy Management for Large Scrapers and Common Proxy Mistakes in Scraping help avoid pitfalls.

Summary

Use this proxy checker to confirm proxy connectivity, exit IP, latency, country, and ASN before using a proxy in production. For rotating proxies, run multiple checks to verify IPs change. Combine with Scraping Test to ensure your target allows the proxy. For reliable scraping at scale, see our Residential Proxies.

Quick tips

For rotating residential proxies, run the checker several times and confirm the exit IP (and country if geo-targeting) changes. If it never changes, you may be on a sticky plan or need to pass a rotation parameter.
Write down the latency and country for each gateway you use; use them when tuning timeouts and when debugging “slow” or “wrong region” issues in production.
Combine with Scraping Test: first check the proxy here, then test the same proxy against your target URL to confirm end-to-end success.

Supported proxy formats

Most providers give you a host, port, and optional username/password. In this checker you can enter host:port or user:pass@host:port. Select HTTP, HTTPS, or SOCKS5 according to your provider. If the checker fails, verify the format in your provider’s docs and ensure your network allows outbound connections to the proxy.
