A research on IPv6 deployment of DNS
Abstruct
Contents
  1. Deployment rate of DNS server on the base of whole .jp domain name
  2. Deployment rate of Mail server on the base of whole .jp domain name
  3. Deployment rate of Web server on the base of whole .jp domain name
Frequency
  • Date: Twice a month
  • on the 1st day and 15th day of every month.
Method
  • This research takes the updated the .jp domain list (which has about 105 million domains as of Sep. 2008) twice a month.
  • It gathers the information about IPv4 and IPv6 capability of each .jp domain servers service like DNS, Mail, and Web from registration information.
  • The current status of IPv6 support on each services are gathered by a result of "dig" command on UNIX environment.
  • Judgment method:
    • DNS server survey: Resolve NS record of target domain and check the address type.
    • Mail server survey: Resolve NS record of target domain and check the address type.
    • Web server survey: Resolve AAAA/A record of www.<domain> and <domain>.
    If AAAA record is exist, the target domain is defined as IPv6 ready.
