IPv6 Implementation Options!

•  There are four choices for migrating to IPv6 while still maintaining IPv4 compatibility •  Building out parallel IPv4 and IPv6 infrastructures •  Running dual stacks on the systems with IPv4 and IPv6 •  Tunneling IPv6 traffic over IPv4 tunnels •  Running IPv6 network address translation (NAT) for IPv4 traffic

•  Any complete solution will likely use a combination of the four choices above

•  All four choices have one thing in common: they all require the company to run and support both IPv4 and IPv6

World IPv6 Day!

•  Wednesday, June 8, 2011 •  Global initiative & test run of the IPv6 protocol •  Goal – Motivate stakeholders to prepare their services for IPv6 •  400+ listed participants •  ~ 40% of participants could be resolved in DNS using exclusively IPv6

•  www.verisigninc.com •  www.verisigninc.com/en_US/why-verisign/innovation-initiatives/ipv6/

index.xhtml •  Dual stacked environment •  Verisign's DNS infrastructure answered almost 607 million queries over

IPv6 on World IPv6 Day •  The 'A' and 'J' root name servers run by Verisign answered 60 million

queries over IPv6 on World IPv6 Day

IPv6 capable com/net Registry!

•  Registry: Accepting “Quad A” records for nearly 10 years •  IPv6 capable through RRP and EPP •  EPP Protocol – RFC 5730 •  EPP SDK •  Shared Registry System (SRS), Whois, Other Registry Services

•  Resolution: IPv6 transport for authoritative com/net Nameservers in 2004

•  Committed to continually expanding capacity to meet and exceed the coming global demand for IPv6

•  Potentially double the traffic on the nameserver infrastructure during the transition years

10!

Enterprise Business!

•  Goal: Ensure customers do not experience differences when connecting via IPv4 or IPv6
