This is advance notice that there is a scheduled change to the IP
address for one of the authorities listed for the DNS root zone. The
change is to L.ROOT-SERVERS.NET, which is administered by ICANN.

the old IP address, and replace it with the new address. In particular,

with the new IP address.
New hints files will be available at the following URLs once the change
has been formally executed:

six months after the transition, but will ultimately be retired from
With kindest regards,
