IP & proxy check tools
See what websites see: your IP, network type, Tor and blacklist status, WebRTC leaks, timezone match and browser fingerprint. Or paste a proxy to check its exit IP.
IP check
Blacklist check (DNSBL)
Public spam and abuse blacklists queried over DNS. IPv6 addresses are not covered by these lists.
WebRTC leak
A leak means your browser exposes a public IP that differs from the IP websites see over HTTP. Tested in your browser only.

DNS leak
Coming soonA real DNS leak test needs our own DNS servers to observe which resolver your device uses. That part is not live yet, so no result is shown here.
Timezone match

Browser fingerprint summary
What any website can read from your browser. Computed on this page only; nothing is sent or stored.
Check my proxy
Paste your trial or purchased proxy. We connect through it once, read the exit IP and run the same IP check. Credentials are never stored or logged.

Frequently asked questions
What do these IP and proxy tools check?
The IP check shows country, region, city, timezone, ISP, ASN and whether the network is mobile, residential (fixed-line) or datacenter. It also checks the official Tor exit list and four public DNS blacklists. Location, ISP and ASN come from the free DB-IP Lite database (IP geolocation by DB-IP), looked up on our own server. In your browser, the page tests for WebRTC leaks, compares your browser timezone with the IP location and summarises what websites can read about your browser.
What do Clean, Caution and Risky mean?
Clean means no blacklist listing, not a Tor exit and no hosting or VPN signal. Caution means one warning signal, such as a datacenter network, a known VPN provider, one blacklist listing or an unidentified network. Risky means a Tor exit or listings on two or more blacklists. Every result lists the exact reasons.
How does "Check my proxy" work?
Paste a trial or purchased proxy (scheme://user:pass@host:port or host:port:user:pass). Our server connects through it once, reads the exit IP and runs the same IP check on that exit IP. The credentials are used only for that one connection and are never stored or logged.
Do you store the IPs or proxies I check?
No. IP addresses and proxy credentials are not written to any database, file or log. We only keep anonymous daily totals, such as the number of checks per country and network type. Checks are limited to 10 per minute per visitor, and proxy checks to one every 5 seconds and 20 per hour.
Why is the DNS leak test marked "coming soon"?
A real DNS leak test needs our own DNS servers that see which resolver your device uses. That part is not live yet, so we show no result instead of a guessed one.
My IP is flagged. What can I do?
Try an SP5 mobile proxy: start a free trial, then paste the trial proxy into "Check my proxy" to see its exit IP, network type and blacklist status before you use it.
