Your public IP address is the address your internet service provider (ISP) assigns to your router or modem. It is visible to every website and service you connect to. This tool detects it from the incoming request headers and looks up additional information from multiple sources including IP geolocation databases and RDAP (Registration Data Access Protocol) for ASN and network ownership data.
An Autonomous System Number (ASN) is a unique identifier assigned to a network or group of networks under a single administrative domain, typically an ISP, university, or large organisation. ASNs are used by the Border Gateway Protocol (BGP) to route traffic across the internet. The ASN shown here identifies who owns the IP block your address belongs to.
A PTR (pointer) record is the reverse of an A record — it maps an IP address back to a
hostname. It is set by your ISP and is often used by mail servers to verify that the sending
IP has a legitimate hostname. Consumer broadband connections typically have a PTR record
like cpe-x-x-x-x.isp.net. No PTR record means the ISP hasn’t configured one.
