We've just launched an opensource golang `ipinfo` cli that lets you quickly and easily get IP address data from the cli. You can lookup geolocation, isp, carrier & vpn  status for a single IP (in much the same way you can by `curl ipinfo.io`) but there's a bunch of additional functionality, including:- bulk lookups of IPs
 - summarize IPs (so get top ASNs, cities etc from a ton of IPs)
 - grepip subcommand to grep for IPs (v4, v6 and bogon flags available)
 - map command to map a bunch of IPsAnd more! See  for more details and installation instructions
