ipinfo [command] [IP|ASN] [options]

ipinfo is the official command-line client for the IPinfo.io API. It returns IP intelligence data including geographic location, ISP, organization, ASN, hostname, and abuse contact information.The tool accepts IP addresses (IPv4/IPv6), ASNs, and CIDR ranges. Multiple inputs can be queried at once or piped in from another command. Output can be rendered as human-readable text, JSON, or CSV, and specific fields can be extracted for use in scripts.The CLI ships with several helper binaries such as grepip, prips, cidr2range, cidr2ip, range2cidr, and mmdb for working with IP lists and MMDB databases.
