D-Root Server Pv4 address change on 3rd Jan 2013.

There is a scheduled change to the IPv4 address for one of the authorities listed for the DNS root zone and the .ARPA TLD announced by Root-Server’s Maintainers.
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 remain unchanged.

This change will to be implemented in the root zone on 3 January 2013, however the new address is currently operational.
It will replace the previous IPv4 address of 128.8.10.90 (also known as TERP.UMD.EDU).

Operators of DNS infrastructure are encouraged to update any references to the old IPv4 address, replacing it with the new one.
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 maintainer notified that old address will continue to work for at least six months after the transition, but will ultimately be retired from service.
