Look up any IP address, anywhere — in under a second.
IPScan turns a raw IP address into something useful: country and city, ISP and ASN, hostname, and signals that hint at proxies, hosting providers, or mobile carriers. Built for sysadmins, security analysts, and curious humans.
One query, the full picture.
Every lookup pulls together registry data, geolocation databases, and reverse DNS so you don't have to bounce between five tools.
Country, region, city
Best-effort geolocation with coordinates, timezone, and postal code. Good for analytics, fraud signals, and content routing.
ISP, organization, ASN
Who actually owns the IP. Useful when you need to distinguish a residential ISP from a datacenter or a corporate uplink.
Proxy, hosting, mobile
Heuristic flags that tell you whether the address is likely a VPN exit, a cloud provider, or a mobile carrier — without claiming certainty.
Network utilities, kept simple.
What's my IP?
Your current public IP, the version (v4/v6), and what the internet sees about your connection.

Plain-English explainers about how IP addresses, geolocation, and routing actually work.
What is an IP address, really?
Every device on the internet has one. But what's actually inside those four numbers (or that long string of hex), and how does the network use them to find you?
IPv4 vs IPv6: why the world is slowly moving on
IPv4 ran out of addresses years ago. IPv6 has been "the future" for decades. We unpack why adoption is patchy and what it means for everyday users.
How IP geolocation actually works (and where it fails)
Geolocation databases are surprisingly accurate at the country level — and surprisingly bad at the street level. Here's what's going on under the hood.
