On 2007-11-02, ISC announced a change to the ip.addr of the L.ROOT-SERVERS.NET server. In updating my root hints, I decided to check the other servers, and sure enough, the B.ROOT-SERVERS.NET server changed at some point in the past. While I am not sure when that happened, and being only one of thirteen it may not make that big a difference to you, this would be a good time to make sure you have current information in your nameservers.
You can download an updated file for BIND servers ftp://ftp.internic.net/domain/named.root
Or you can edit your Windows server’s Root Hints through the gui.
You can also look these up using dig
dig @198.41.0.4 -t ns [enter]
A.ROOT-SERVERS.NET. 3600000 IN A 198.41.0.4
B.ROOT-SERVERS.NET. 3600000 IN A 192.228.79.201
C.ROOT-SERVERS.NET. 3600000 IN A 192.33.4.12
D.ROOT-SERVERS.NET. 3600000 IN A 128.8.10.90
E.ROOT-SERVERS.NET. 3600000 IN A 192.203.230.10
F.ROOT-SERVERS.NET. 3600000 IN A 192.5.5.241
G.ROOT-SERVERS.NET. 3600000 IN A 192.112.36.4
H.ROOT-SERVERS.NET. 3600000 IN A 128.63.2.53
I.ROOT-SERVERS.NET. 3600000 IN A 192.36.148.17
J.ROOT-SERVERS.NET. 3600000 IN A 192.58.128.30
K.ROOT-SERVERS.NET. 3600000 IN A 193.0.14.129
L.ROOT-SERVERS.NET. 3600000 IN A 199.7.83.42
M.ROOT-SERVERS.NET. 3600000 IN A 202.12.27.33
So, don’t forget to change set your clocks, change the batteries in all smoke and CO detectors, and verify your root hints are correct!
