Country and ISP diversity are approximated by resolving IP addresses to a country code and an autonomous system. We process the capabilities and properties relays and bridges reported to directory authorities.
This graph shows the number of relays supporting IPv6 as compared to all relays. A relay can support IPv6 by announcing an IPv6 address and port for the OR protocol, which may then be confirmed as reachable by the directory authorities, and by permitting exiting to IPv6 targets. These sets are not distinct, because relays can have various combinations of announced/confirmed OR ports and exit policies.
