D-Root is Changing its IPv4 Address on January 3, 2013
This is advance notice that there is a scheduled change to the IPv4 address
for one of the authorities listed for the DNS root zone and the .ARPA TLD.
The change is to D.ROOT-SERVERS.NET, which is administered by the University
of Maryland.
The new IPv4 address for this authority is 199.7.91.13
The current IPv6 address for this authority is 2001:500:2d::d and it will
continue to remain unchanged.
This change is anticipated to be implemented in the root zone on January,
3 2013, however the new address is currently operational. It will replace
the previous IP address of 128.8.10.90 (also once known as TERP.UMD.EDU).
We encourage operators of DNS infrastructure to update any references to
the old IP address, and replace it with the new address. In particular,
many DNS resolvers have a DNS root hints file. This should be updated with
the new IP address.
New hints files will be available at the following URLs once the change
has been formally executed:
- http://www.internic.net/domain/named.root
- http://www.internic.net/domain/named.cache
The old address will continue to work for at least six months after the
transition, but will ultimately be retired from service.
