ipterm: IP lookups from the command line. No key, no sign-up, no cookies.

YOUR OWN ADDRESS (from Cloudflare's edge: no third-party lookup)
  curl ipterm.net            your IP address
  curl ipterm.net/json       your IP, network and location as JSON
  curl ipterm.net/asn        your network's AS number
  curl ipterm.net/org        your network's name
  curl ipterm.net/cc         your country code (ISO 3166-1)
  curl ipterm.net/city       your city
  curl ipterm.net/tz         your time zone
  curl ipterm.net/colo       the Cloudflare data center that answered you
  curl ipterm.net/hostname   your reverse DNS name

ANY ADDRESS
  curl ipterm.net/8.8.8.8           owner, network and location as JSON
  curl ipterm.net/8.8.8.8/country   one value: asn, org, cc, country,
                                    continent or hostname

NETWORKS, DNS, REGISTRY RECORDS, SUBNETS
  curl ipterm.net/AS13335            a network and its address blocks
  curl ipterm.net/dns/example.com    DNS records; add /MX for one type
  curl ipterm.net/whois/github.com   registry record: domain, IP or ASN
  curl ipterm.net/cidr/10.0.0.0/22   subnet calculator

TEXT INSTEAD OF JSON
  Add ?format=text to any lookup for aligned lines, like the web terminal.
  Quote the URL so the shell leaves the ? alone:
  curl 'ipterm.net/8.8.8.8?format=text'

NOTES
  One-value answers are one line. A missing value is an empty line with
  HTTP 404, so  curl -fs ipterm.net/city  exits non-zero.
  30 uncached lookups a minute per address, then HTTP 429.
  No cookies or tracking, and nothing about you is stored: ipterm.net/privacy
