IP Lookup & Purity Check — IP Reputation, VPN & Proxy Detection

Q: How is an IP lookup different from an IP purity check?

An IP lookup answers "where is this IP and who owns it" — location and ISP. A purity check goes further and answers "is this IP clean" — whether it is flagged as a proxy or datacenter, whether it appears on blocklists, and how platform risk systems are likely to treat it. This site gives you both at once.

Q: How do I find out what my own IP address is?

You do not have to do anything — opening this page detects and displays your current outbound public IP automatically. If you have both IPv4 and IPv6, the page offers a switch to view the address of the other protocol family.

About IP Lookup and Purity Check

This page automatically looks up your current public IP address ("what is my IP") and returns a full report: location (country / region / city), ISP and ASN, rDNS hostname, IP type, and a 0–100 purity score. On a VPN or proxy it also shows straight away whether that exit is flagged as a VPN or proxy, whether it is on blocklists, and whether DNS or WebRTC leaks. To check a different address, enter any IPv4, IPv6, domain or ASN in the search box above.

IP purity measures how much a given IP is trusted by platform risk-control systems — the higher the score, the cleaner the IP. CleanIP cross-checks 20+ independent data sources; geolocation alone is compared across 8 of them. When sources disagree, the page flags the confidence level and the likely reason instead of presenting a single deceptively certain answer.

Six checks for VPN and proxy users

VPN detectionWhether this IP is flagged as a VPN exit, and which VPN provider it belongs to
Proxy detectionWhether it is flagged as a proxy server, including residential proxies, Tor and privacy relays
IP reputationAbuse reports, DNSBL and blocklist records, plus a 0–100 CleanIP Score
Datacenter detectionDatacenter (IDC) / residential broadband / mobile network, with native vs broadcast IP
ASN lookupISP, ASN number, network type and IP geolocation
DNS / WebRTC leak testWhether your browser exposes your real network over DNS or WebRTC while on a VPN — one click to test
