IP address lookup: location, ISP, ASN and risk check
Enter any public IPv4 or IPv6 address to see its country, region, city, ISP, ASN, CIDR range and RDAP registration data, plus a reputation score and proxy, VPN, Tor, datacenter and crawler flags.
Location comes from several providers in turn (ipwho.is, GeoJS, ipapi.is), requested and cached by our Worker so browser extensions cannot block it. The reputation score comes from Net.Coffee; if that source is down the score is simply hidden and the location is still shown.
Typical uses: checking whether a proxy or VPN node is seen as datacenter traffic, investigating account risk checks, tracing an unfamiliar login IP, or verifying who owns a server or CDN address.
How to use
- Paste an IP and press Enter, or open /network/ip/<IP> directly.
- Review the score and flags; higher scores look more like ordinary residential traffic.
- Copy individual values or share the page URL.
FAQ
What is an ASN?
An autonomous system number identifies a network such as an ISP or cloud provider, e.g. AS13335 is Cloudflare and AS15169 is Google.
Why does “datacenter IP” matter?
Cloud and hosting addresses are often treated as non-residential traffic and may trigger captchas or fraud checks.
Can I look up a private IP?
No. Private and reserved ranges such as 192.168.0.0/16 and 10.0.0.0/8 have no public location data.
