IPv6 Enabled Network (JP)

The following figures show the Ratio of IPv6 Enabled Internet Backbones in Japan.

We measure the number of IPv6 enabled of Transit AS in BGP routing tables.The percentage of IPv6 enabled network is obtained by dividing the number of AS that is advertising the IPv6 routing information by the total number of AS. Mapping for each country from the AS number is using a delegate list of the RIR. The delegate list of APNIC is here. The percentage of IPv6 enabled network for the origin AS is here.
