IP Lookup API
Look up any IPv4 or IPv6 address with one call: the ipbase IP API returns its country, city, ISP, ASN, time zone and, on the Small plan and above, VPN, proxy and Tor flags. ipbase.com provides a reliable & scalable IP API for software developers. It uses a database of IP addresses associated with cities and other relevant information like time zone, latitude & longitude.
