BIND now comes with a baked in roots file (in the imaginatively named

Not (at least by that name) in the Redhat/Centos 6.3 bind 9.8.2.
Nope -- it is in lib/dns/rootns.c in the source code tree….
Oh, of course...
When BIND is compiled into a binary this gets baked in….
You can verify this by running strings on the binary. E.g:
wkumari$:~$ strings /usr/local/sbin/named | grep A.ROOT-SERVERS.NET
. 518400 IN NS A.ROOT-SERVERS.NET.
A.ROOT-SERVERS.NET. 3600000 IN A 198.41.0.4
A.ROOT-SERVERS.NET. 3600000 IN AAAA 2001:503:BA3E::2:30
Mine is located in /usr/sbin/ and no such string. In fact the only
occurance of ROOT is a comment on the location of the ROOT KEY.
And anyway, baking it in is a problem as we continue to have an
availablity of AAAA for the roots.
There is no need for a named.root file, and is just another thing to go wrong…
Is there anything needed in the named.conf to actuate this if you do have it?

The Centos 6.3 bind and bind-chroot do not seem to come with a named.root.
Does have a named.ca, though.
So from my old named.root.hints include (also not provided; where did I get
this?) I tried:
wget ftp://ftp.rs.internic.net/domain/named.root
And got a nice looking named.root last updated 1/3/2013, with nice comments on
who use to run the various root servers.
Then I tried:
dig . ns @198.41.0.4 > named.root
I see where this addr is the A root server, anyway, the response did not have A
records for B, E, I, J, or L !!! And of course no AAAA records for I, J, or L.
It has NS records for A thru M.
What went wrong here?
Which do I use?
