Network by IP Address API

This API returns detailed information about the active network a specific IP address belongs to, including the Autonomous Systems (AS) that announce and serve that network — registration details, IP prefix, and neighbouring system relationships.

It's useful when you need network-level context rather than geographic location: identifying the ISP or organisation behind an IP, understanding the network topology, or enriching logs and analytics with provider information.

Parameters

Parameter	Type	Required	Description
`ip`	string	Optional	IPv4 IP address in a string or numeric format or IPv6 IP address in a string format. If omitted, the caller’s IP address is assumed
`localityLanguage`	string	Optional	Preferred language for locality names in ISO 639-1 format, such as 'en' for English, 'es' for Spanish etc. If the requested language is not available for a requested location, it will default to English. If no English variant is known, will provide the native, local names
`key`	string	Optional	Your API key

Response Schema

ipstringRequested IP address in a string format

registrystringThe Regional Internet Registry (RIR) that administers the network block (e.g. ARIN, RIPE, APNIC, LACNIC, AFRINIC, IANA).

registryStatusstringThe registration status of the network block as recorded by the RIR (e.g. "assigned", "allocated", "reserved").

registeredCountrystringRegistered Country ISO 3166-1 Alpha-2 code

registeredCountryNamestringRegistered Country name localised to the language is as defined by 'localityLanguage' request parameter

organisationstringThe organisation or entity the network block is registered for, as recorded in the RIR database.

isReachableGloballybooleanIndicates whether the network was announced on BGP and reachable globally or not

isBogonbooleanIndicates whether the IP address is excluded from public Internet use by the authorities but announced into the global routing table via BGP

bgpPrefixstringThe BGP prefix detected on the global network, announcing the network

bgpPrefixNetworkAddressstringThe first (network) address of the BGP prefix range.

bgpPrefixLastAddressstringThe last (broadcast) address of the BGP prefix range.
