Anonymous IP address: Identifies whether an IP address is associated with privacy services such as VPNs, proxies, Tor nodes, or relay services.
Carrier information: Provides details about the mobile carrier, including the carrier name, Mobile Country Code (MCC), and Mobile Network Code (MNC).
Network flags: Anonymous IP address (VPN, proxy, Tor, or relay), Hosting IP address (data center or server IP), Anycast IP, Carrier mobile IP flag, and Satellite IP address

Carrier IP address

VPN IP address

The IPinfo Plus also supports ASN lookups via the ASN API.

The API endpoint also supports explicit declaration of IP address connections (IPv4/IPv6).

Description	Endpoint type	Endpoint
General (Dual Stacked)	Self / Client IP	`curl https://api.ipinfo.io/lookup/me?token=$TOKEN`
General (Dual Stacked)	Lookup / Target IP	`curl https://api.ipinfo.io/lookup/8.8.8.8?token=$TOKEN`
IPv4	Self / Client IP	`curl https://v4.api.ipinfo.io/lookup/me?token=$TOKEN`
IPv4	Lookup / Target IP	`curl https://v4.api.ipinfo.io/lookup/8.8.8.8?token=$TOKEN`
IPv6	Self / Client IP	`curl https://v6.api.ipinfo.io/lookup/me?token=$TOKEN`
IPv6	Lookup / Target IP	`curl https://v6.api.ipinfo.io/lookup/8.8.8.8?token=$TOKEN`

The general API endpoint is built to support both IPv4 and IPv6 connections, ensuring compatibility with either protocol.

Alternative API Schema

Our legacy API is still maintained with fresh data, and we are committed to providing continued service to existing customers.
