Proxy Tools for Testing, Formatting and IP Checks

Use this hub to test proxy speed, format proxy lists, check IP locations, inspect WHOIS records, trace routing, and review blacklist or anonymity signals before a proxy goes into production.

Longer-term context

Compare a point-in-time test with monthly results

A single test describes one route at one moment. Review the monthly proxy performance report for aggregated regional latency bands and success counts.

Choose by task

Find the right proxy tool faster

Each tool answers a different question. Start with the job you are trying to finish, then move the same proxy list through the next check if needed.

Test proxy quality

Confirm reachability, speed, reputation, and privacy signals before a proxy is assigned.

Health check Proxy Tester Test proxy status, speed, protocol support, and basic connectivity. Run test Latency Proxy Region Speed Test Compare response time from multiple regions and testing targets. Compare speed Reputation Proxy Blacklist Checker Check proxy IPs against DNSBL and reputation signals. Check lists Headers Proxy Anonymity Checker Inspect detected exit IP, anonymity level, and forwarded proxy headers. Check privacy

Format and manage proxy lists

Clean mixed proxy formats so tools, scripts, and browser add-ons receive a consistent list.

List cleanup Proxy Formatter Convert proxy lists between ip:port, user:pass, URL, CSV, cURL, and code formats. Format list

Investigate IPs and routing

Look up geography, network ownership, ASN data, reverse DNS, and route hops.

Geo check IP Location Checker Check proxy IP countries, regions, cities, ISPs, and coordinates. Check location Ownership IP WHOIS Review IP ownership, ASN, network, and registration details. Inspect IP Route map Traceroute IP Trace network routing to a public IP, hostname, or proxy endpoint. Trace route

Practical examples

From a raw proxy to a usable result

Use these short workflows to choose the right input, run only the checks you need, and record an output that can be compared later.

Input example

Normalize a mixed proxy list

host:port:user:password

Run the Proxy Formatter first, choose the format accepted by your application, then test the normalized list.

Expected output: one consistent proxy per line with no missing fields.

Input example

Compare connection quality

proxy + protocol + timeout

Run Proxy Tester, then compare regional latency only for endpoints that pass the connectivity check.

Expected output: status, response time, visible exit IP and a repeatable timeout rule.

Input example

Verify location and reputation

visible exit IP

Check IP location, ownership and blacklist signals separately so one database result is not treated as the whole answer.

Expected output: confirmed country, ASN or owner, DNSBL observations and the test date.

Recommended workflow

Validate a proxy list before assigning it to a project

  1. Format it: normalize mixed proxy formats with the proxy formatter.
  2. Test it: check status, speed, protocol support, and failures with the proxy tester.
  3. Verify the IPs: check locations, WHOIS records, routing, blacklist status, and anonymity headers.
  4. Assign only clean proxies: use stronger proxies for account workflows, social media, scraping, SEO tools, and automation.

FAQ

Proxy tools FAQ

Which tool should I use first?

Start with the proxy formatter if your list has mixed formats. Then use the proxy tester to check reachability and speed.

How do I check where a proxy is located?

Use the IP location checker for country, region, city, ISP, and coordinate details, then use WHOIS if you need ownership and ASN information.

How do I check if a proxy is risky?

Use the blacklist checker for DNSBL and reputation signals, then use the anonymity checker to see whether the proxy exposes forwarding headers.

Can I buy proxies after testing?

Yes. The hub links to dedicated and semi-dedicated proxy plans so visitors can move from testing to an appropriate proxy plan.
