RE: NetSol screwing the pooch?

  • From: Newell, Tom

Eric,

if you would have looked at the NS set for COM (instead of 
the NS set for .), you would have found that authoritive hosts 
for COM are:

com.			6D IN NS	A.ROOT-SERVERS.NET.
com.			6D IN NS	G.ROOT-SERVERS.NET.
com.			6D IN NS	F.GTLD-SERVERS.NET.
com.			6D IN NS	F.ROOT-SERVERS.NET.
com.			6D IN NS	B.ROOT-SERVERS.NET.
com.			6D IN NS	I.ROOT-SERVERS.NET.
com.			6D IN NS	E.ROOT-SERVERS.NET.
com.			6D IN NS	J.GTLD-SERVERS.NET.
com.			6D IN NS	K.GTLD-SERVERS.NET.
com.			6D IN NS	A.GTLD-SERVERS.NET.
com.			6D IN NS	H.GTLD-SERVERS.NET.
com.			6D IN NS	C.GTLD-SERVERS.NET.

 
...and their serials are:


Server                  COM.		Operator	
a.root-servers.net      2000041301	NSI
g.root-servers.net	2000041301	DOD
f.gtld-servers.net	2000041301	NSI
f.root-servers.net	2000041301	ISC
b.root-servers.net      No answer   ISI
i.root-servers.net	2000041301	Sweden (Royal Inst of Tech)
e.root-servers.net	2000041300	NASA
j.gtld-servers.net	2000041301	NSI
k.gtld-servers.net	2000041301	NSI
a.gltd-servers.net	2000041301	NSI
h.gtld-servers.net	2000041301	NSI
c.gtld-servers.net	2000041301	NSI


So in every case where NSI operates the host NS for COM, you
should see that the serialization is correct.  In those cases
where a traditional root server still serves COM, should
they get out of synch, our NOC contacts them to encourage
resolution.  However, as the host is not an NS operated by NSI, 
beyond encouraging them to fix the problem, there is little we 
can do.  This is part of the reason for moving COM off of the
traditional roots in just the same fashion as other first
level delegations are managed today.
