IP Address Lookup
Enter any IPv4 address to see its geolocation (country, region, city), the ISP or hosting provider behind it, its ASN, and whether it's flagged as a known proxy or VPN exit node. Useful for investigating suspicious traffic, verifying a proxy's claimed location, or just satisfying curiosity about where an address resolves to.
Proxy Checker
Paste your proxy list and get instant health diagnostics, geo info, and anonymity detection.
| Status | Proxy | Protocol | Exit IP | Country | Type | ASN | ISP | Latency | Flags |
|---|
Target URL Proxy Check NEW
Test proxies against a specific target URL. Find out which ones actually work for scraping your target, not just which ones are alive. Detects WAF blocks (Cloudflare, DataDome, Akamai, Imperva, PerimeterX) and CAPTCHAs.
| Status | Proxy | Protocol | HTTP | Latency | Block Reason |
|---|
Port Scanner
Scan any host for open ports. Checks 22 common service ports by default, or specify your own.
| Port | Status | Service | Latency |
|---|
Ping
Measure round-trip latency to any host. Returns min/avg/max and packet loss percentage.
My IP
See your public IP address, location, ISP, and whether you're detected as a proxy or datacenter.
IP Lookup
Look up geolocation, ISP, and metadata for any IP address.

Frequently asked questions
How accurate is IP geolocation?
Country-level accuracy is generally reliable. City-level accuracy varies a lot, mobile and satellite IPs especially can resolve to a city far from the actual user, since geolocation databases map IP ranges to ISP registration addresses, not real-time device location.
Why does this IP show as a datacenter but my proxy provider says it's residential?
Some providers lease IP ranges from datacenters and market them as residential. This lookup checks the actual ASN and registration data, which can expose that mismatch. See the fake-residential flag in proxy checker results for the same detection.
What is an ASN?
An Autonomous System Number identifies which network operator controls a block of IP addresses. It's a more reliable way to identify the actual owner of an IP than reverse DNS alone, which can be missing or misleading.
Can I look up my own IP with this?
Yes, but the dedicated What Is My IP tool is built specifically for that and shows your own connection's details directly without needing to type anything.
