\nThis is advance notice that there is a scheduled change to the IP addresses
\nfor one of the authorities listed for the DNS root zone and the .ARPA TLD.
\nThe change is to H.ROOT-SERVERS.NET, which is administered by the U.S. Army
\nResearch Laboratory.<\/p>\n
The new IPv4 address for this authority is 198.97.190.53.<\/p>\n
The new IPv6 address for the authority is 2001:500:1::53.<\/p>\n
This change is anticipated to be implemented in the root zone on 1 December
\n2015, however the new addresses are operational now. They will replace the
\nprevious IP addresses of 128.63.2.53 and 2001:500:1::803f:235 (also
\npreviously known as AOS.BRL.MIL and AOS.ARL.ARMY.MIL).<\/p>\n
We encourage operators of DNS infrastructure to update any references to the
\nold IP addresses and replace them with the new addresses. In particular,
\nmany DNS resolvers have a DNS root “hints” file. This should be updated with
\nthe new IP addresses.<\/p>\n
New hints files will be available at the following URLs once the change has
\nbeen formally executed on December 1:<\/p>\n
http:\/\/www.internic.net\/domain\/named.root
\nhttp:\/\/www.internic.net\/domain\/named.cache<\/p>\n
The old IPv4 address will continue to work for six months after the
\ntransition (until 1 June 2016), at which point it will be retired from
\nservice. The address will remain under the control of the Army Research
\nLaboratory, never to be used again for DNS service. The old IPv6 address
\nwill continue to work indefinitely, but may ultimately be retired from
\nservice.<\/p>\n
Simultaneous to the retirement of the old address on June 1, 2016, the
\nASN for H-root will change from 13 to 1508.<\/p>\n
You can monitor the transition of queries to the new addresses at the
\nfollowing URL:<\/p>\n
