This page displays an overview of IPv6 host adoption around the world. A 'host' is a computer connected to a network, in this case it defined by a hostname entry in the DNS records for a domain (eg. www.example.com, mx.example.com or ns1.example.com). A host may have have IPv4, IPv6 or both types of IP addresses listed in its DNS record using A and AAAA entries. If a host has a valid AAAA record it is considered an IPv6 enabled host. The data shows the percentage of IPv6 uptake over time.
