This change appears to have been completed, as of root zone serial =
2013010300:
[krill:~]% host d.root-servers.net
d.root-servers.net has address 199.7.91.13
d.root-servers.net has IPv6 address 2001:500:2d::d
[krill:~]%=20
[krill:~]% curl -s ftp://rs.internic.net/domain/named.root | fgrep =
D.ROOT
. 3600000 NS D.ROOT-SERVERS.NET.
D.ROOT-SERVERS.NET. 3600000 A 199.7.91.13
D.ROOT-SERVERS.NET. 3600000 AAAA 2001:500:2D::D
[krill:~]%=20
The authoritative location of the root hints file is =
<ftp://rs.internic.net/domain/named.root> and those who feel like being =
tidy DNS admins could pull a fresh copy from there so that the next time =
their nameserver is restarted it will prime optimally.
As discussed at some length before, those who prefer to be more =
hands-off about this will very likely see no negative impact from their =
laziness.
