Not sure if your proxy is actually working? xProxy Market's free Proxy Checker tests liveness, response time, geolocation, DNS leaks, and TCP/IP fingerprint — no signup required.
You bought a proxy plan, copy-pasted the credentials into your app — and nothing works. Or worse: it seems to work, but you're not sure which country the exit IP is in, whether there's a DNS leak, or if the IP is flagged as datacenter.
That's exactly what a proxy checker solves.
xProxy Market's free Proxy Checker gives you a full diagnostic on any proxy in seconds — no account needed.

A basic ping just tells you if a server is reachable. A good proxy checker tells you how the proxy behaves from the outside world — which is what actually matters when you're using it for scraping, automation, or anonymity.
Here's what xProxy Market's checker tests:
The most obvious check: can the proxy actually connect to the internet?
The checker attempts a real outbound request through your proxy and reports:
Status — Live ✅ or Dead ✗ Exit IP — the IP address the target website actually sees (may differ from the proxy host) Response time — measured in milliseconds (good proxies are under 500ms; mobile proxies can vary more) Protocol — confirms which protocol (HTTP, HTTPS, SOCKS5) the proxy is responding on
Why exit IP matters: some proxy services route through an intermediary, so the IP you connect to is not the IP that websites see. The checker shows you the real exit IP.
Once the proxy is confirmed live, the checker looks up the exit IP's geolocation:
| Field | What It Tells You | |---|---| | Country | Where the IP is registered | | Region / City | Approximate location | | ISP | Internet Service Provider name | | Organization | The company that owns the IP block | | ASN | Autonomous System Number (useful for identifying carriers) | | Timezone | Local timezone of the exit node | | Mobile | Whether the IP is classified as a mobile/carrier IP | | Hosting / DC | Whether the IP is flagged as a datacenter or hosting provider |
The Mobile and Hosting/DC flags are especially important. Many anti-bot systems (Cloudflare, DataDome, PerimeterX) automatically distrust IPs flagged as hosting or datacenter. If you need to pass as a real user, you want Mobile: Yes and Hosting/DC: No.
A DNS leak is when your device resolves domain names through a DNS server that isn't the proxy — revealing your real ISP or location to the websites you visit.
The checker tests this by seeing which DNS servers are actually used when requests go through your proxy, and reports:
Number of DNS servers found The ISP each DNS server belongs to The location of each server
No leak = DNS queries are resolved through the proxy's network. If you see your home ISP appearing in the DNS results, the proxy has a DNS leak.
This is the most advanced check — and unique to xProxy Market's tool.
Every TCP connection has a fingerprint based on low-level network parameters. Sophisticated bot detection doesn't just look at IP addresses — it analyzes the TCP/IP stack itself to guess what operating system and network type is behind the connection.
The checker reports:
| Field | Meaning | |---|---| | OS | Operating system detected from TCP/IP stack | | MTU | Maximum Transmission Unit — differs between network types (WiFi, LTE, etc.) | | Link Type | Ethernet, mobile, tunnel, etc. | | Distance | Number of network hops between proxy and our checker | | JA4T | TCP fingerprint hash — used by advanced detection systems |
Why does this matter? A datacenter proxy sitting in a Virginia AWS rack will have a very different TCP fingerprint than a real 4G phone in London. High-end anti-bot systems flag mismatches between geolocation and TCP fingerprint. Mobile proxies from xProxy Market produce authentic carrier-grade TCP signatures.
