IP Address Lookup

An IP lookup takes an IPv4 or IPv6 address and returns what is publicly known about it: the approximate geographic location (country, region and city), the network that owns it expressed as an ASN, the ISP or organization name, the timezone, and the reverse DNS hostname if one is published. It does not reveal a person or a street address — geolocation is tied to the network operator, not the individual user. It is useful for understanding where a server sits, who hosts it, and whether traffic is coming from where you expect.

Country-level accuracy is very high, usually well above 95 percent. City-level accuracy is far less certain because it is inferred from registration data and network routing, not GPS, so it can be off by tens or even hundreds of kilometres, especially for mobile carriers, VPNs, and large cloud providers whose addresses are announced from a central location. Treat the city as a hint, not a fact, and rely on the ASN and ISP fields when you need certainty about which network an address belongs to.

An ASN, or Autonomous System Number, identifies a network that controls a block of IP addresses and announces routes for them on the internet — for example AS15169 is Google. The ASN is the most reliable signal in an IP lookup because it tells you exactly which operator is responsible for the address, regardless of how fuzzy the city estimate is. It is the field network engineers use to confirm whether traffic belongs to a cloud provider, a hosting company, a residential ISP, or a corporate network.

Private, loopback, and reserved ranges — such as 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, 127.0.0.0/8, the link-local 169.254.0.0/16 block, and IPv6 equivalents like ::1 and fe80:: — are not routable on the public internet and have no global owner or location, so there is nothing meaningful to geolocate. The tool detects these and tells you rather than returning a misleading result. Enter a public address to get a real answer.

A reverse DNS lookup goes the opposite direction from a normal one: instead of turning a hostname into an IP, it turns an IP into the hostname its owner has published for it, via a PTR record. Mail servers commonly use reverse DNS to judge whether a sending IP is legitimate, and it can hint at what a server is used for. Not every address has a PTR record, so a blank reverse DNS field simply means none is published — it is not an error.

Your public IP address is shown at the top of this page — it is the address your internet connection presents to every website and server you visit, assigned by your ISP. It is different from your private LAN address (like 192.168.x.x): it is the single public address your whole network shares. Because geolocation, rate limits and many access controls work from this address, it is the one that identifies your connection online.
