[dns-operations] Question about L-Root IP address

[Yasuhiro Orange Morishita / 森下泰宏]

Hello, DNS operators:

I found the following description in Peter and Matt's I-D.

It describes IP address changes of L-Root was twice.  But I couldn't
find only once, in 2007.

I checked the past root hint file in Aug 22 1997,
<https://lists.isc.org/pipermail/bind-users/2003-January/044241.html>
But its L-Root address is 198.32.64.12, I think it was used until 2007.

If you know the information about it, please let me know.

   The list of root name servers has been rather stable over the last
   ten years.  After the last four servers had been added and moved to
   their final (network) destinations in 1997, there have been only four
   address changes affecting the L (twice), J, and B servers.  Research
   is available for B [Mann2006] and J [BLKT2004], which shows that
   several months or even years after the change had become effective,
   traffic is still received on the old addresses.  Therefore, it is
   important that resolvers be able to cope with change, even without
   relying upon configuration updates to be applied by their operator.
