IP Lookup
Understanding IP Address Lookups
Every device connected to the internet is assigned an IP address, a unique numerical label that enables communication across networks. An IP lookup reveals detailed information about an address, including its geographic location, the network it belongs to, the organization that operates it, and whether it is associated with a VPN, proxy, or Tor exit node.
Our IP lookup tool combines data from multiple sources: geolocation databases map IP addresses to physical locations, BGP routing tables identify the Autonomous System (AS) that advertises the address, and RDAP (Registration Data Access Protocol) queries retrieve official registration records from Regional Internet Registries such as ARIN, RIPE NCC, APNIC, LACNIC, and AFRINIC.
IP Lookup Data Explained
IP Geolocation
Maps an IP address to a physical location using databases that correlate IP ranges with geographic data from RIRs, ISPs, and crowdsourced measurements.
ASN (Autonomous System)
Identifies the network operator responsible for a block of IP addresses. Each AS is assigned a unique number and exchanges routes via BGP.
IPv4 vs IPv6
IPv4 uses 32-bit addresses (4.3 billion total), while IPv6 uses 128-bit addresses for a virtually unlimited supply. Both are actively used on the modern internet.
RDAP Registration
RDAP is the modern replacement for WHOIS, providing structured registration data including the network range, organization, abuse contacts, and registration dates.
Privacy Detection
Identifies whether an IP address is associated with a VPN, proxy server, Tor exit node, relay, or hosting/datacenter provider, useful for fraud prevention and security.
Reverse DNS (PTR)
Resolves an IP address back to a hostname via PTR records. Often used to verify mail server identity and for network diagnostics.
