Do I need to register?

No, the tools work without registration.

Where do I start checking a proxy?

Check the proxy in the proxy checker, connect it and open My IP: the address and country should change. Then run the DNS Leak Test.

How is IP Lookup different from My IP?

My IP shows your current address. IP Lookup shows data about any address you enter.

Yes, all tools in this section are free. Only request rate limits apply to protect the service from abuse.

Can I check proxies from another provider?

Yes, the proxy checker works with any proxies in the IP:PORT or IP:PORT:LOGIN:PASSWORD format.

Proxy and IP tools

Check your IP, any address, proxies, open ports, the route to a server, ping and DNS leaks — free, in the browser and without registration.

Which tool to choose

Every tool works in the browser, with no registration or installation. Pick one by task:

Task	Tool	What you get
Find your IP and check whether it changed after connecting a proxy	My IP	IP, country, city, provider, browser and OS
Find where any IP is located and who owns it	IP Lookup	Country, city, provider, ASN, network type
Check a proxy list before work	Proxy Checker	Status, type, country, speed, anonymity
See which ports are open on your server	Port Scanner	The status of every port: open, closed, filtered
Find where speed is lost on the way to a server	IP Tracer	Route hops with latency and loss on each
Make sure a proxy or VPN does not expose your real address	DNS Leak Test	DNS servers, WebRTC and IPv6 leaks
Check whether a server responds and how fast	Ping	Time of every packet, loss, minimum, average and maximum

How to check a proxy before work

A proxy that “seems connected” does not always work as needed: it may not respond, be in a different country or expose your real address through DNS. A check takes a couple of minutes and saves hours of debugging later.

1
Paste the proxy into the proxy checker — see whether it responds, its type and country.
2
Connect the proxy in your browser or app and open My IP — the address and country should change to the proxy ones.
3
Run the DNS Leak Test — DNS servers and WebRTC must not show your real address and country.
4
If something is wrong, check the server port, ping or the route to it.

Terms in brief

Term	What it is
IP address	The address of a device or network on the internet. Websites see your public IP and use it to tell your country and provider.
Proxy	An intermediary server: a website sees the proxy IP instead of yours.
Port	The number of an “entrance” on a server behind which a particular service runs: 80 — a website over HTTP, 22 — SSH.
DNS	The system that turns a website name into an IP address. If DNS queries bypass the proxy, a website can learn your real region.
ASN	The number of the network that owns a block of IP addresses: it shows the provider or hosting company.
WebRTC	A browser technology for calls and video. It can reveal your real IP to a website even through a proxy.
Ping	The time a packet takes to reach a server and come back, in milliseconds.
