IPv6 Set for Root Adoption?

IPv6 adoption has a key adoption deadline looming this year, but is still facing plenty of barriers to adoption. Key among them is this: IPv6 address information is not included in most of the root DNS servers that power the Internet. This makes IPv6 to IPv6 connections a difficult proposition.

At a time when the current IPv4 protocol is running out of address spaces for Web sites, the barriers to IPv6 adoption need to be addressed, experts say.

Starting on February 4th, at least one of those adoption barriers will be addressed as AAAA records for IPv6 addresses are added to four of the key root DNS servers. IPv6 AAAA records are a key resource record type for storing IPv6 address information on DNS servers. The IPv6 AAAA additions were announced by ICANN at the end of December in an e-mail announcement by Barbara Roseman, general operations manager for Internet Assigned Numbers Authority, an organization working under the auspices of the Internet Architecture Board (IAB), and which is responsible for assigning new Internet-wide IP addresses.

The inclusion of the IPv6 records could make the adoption and operation of IPv6 a more viable option for network operators.

For Paul Vixie, president of the Internet Systems Consortium and an operator of the F root DNS server and creator of the popular BIND DNS software, the ICANN/IANA move to IPv6 is a very good thing.

"This is one of the roadblocks to running an Internet device IPv6-only, and we're very glad to finally see this roadblock removed," Vixie told InternetNews.com.

Vixie isn't the only one that is enthusiastic about the ICANN/IANA announcement of AAAA for IPv6 on some root DNS servers. Internet service provider Verio is also keen on the move.

"The ICANN/IANA announcement of AAAA for IPv6 on root DNS servers is the first step toward having a worldwide IPv6-capable DNS system," Fred Clift, manager of VPS/MPS development for Verio, told InternetNews.com.

"Since the DNS system is distributed across thousands of organizations, nations, companies etc., this is the logical and much needed first step. In the future, a majority of the Internet will need to be reachable via IPv6; the ICANN/IANA announcement is part of the progression towards this."
