[sig-dns] NANOG 40 report

[Edward Lewis <Ed.Lewis@neustar.biz>]

The North American Network Operators Group meeting number 40 met last 
week in Bellevue, Washington.  Surprisingly, the number attendees 
from one particulay economy in the APNIC region (Japan) got it ranked 
as the second or third in the list by economy - the reason given was 
that there was a NTT/Verio meeting also being held.

The agenda, with links to presentations, is here:

There were two presentations on DNS given during the week.  One was 
given by Hyo-Jeung Shin of KT (KORNET) on a monitoring and analysis 
system that watched the behavior of recursive servers.  One comment 
from the floor was that is was innovative to see someone looking at 
the effectiveness of caching (via measuring the cache hits and 
misses).

There hasn't been too much published on the behavior of caching 
servers, most work is done through observations of authoritative 
servers.  Generally authoritative servers are run by registries and 
web hosting (like) operators who are concerned with making sure DNS 
data "gets out there."  Recursive servers are mostly run by ventures 
like ISPs that seem to treat DNS as a necessary evil for their 
subscribers.  So it is interesting to see an ISP engineer speak up on 
the topic.

The second presentation was a quicky prepared ("lightening") talk on 
moving DNS servers to IPv6.  The title sums up the message pretty 
well "IPv6: The Water's Fine, Jump In."

Overall, it was quite notable that IPv6 was *not* covered in the 
first published NANOG agenda.  The Lightening talk mentioned above 
was added in the middle of the conference partly due to a criticism 
that NANOG was overlooking IPv6 and there was a BoF on ULA (Unique 
Locally Assigned) addressing.  The BoF on ULA was too hastily 
arranged to contain a complete discussion on the topic.

The observation about IPv6 is in shard contrast to discussions 
ongoing in ARIN (North American version of APNIC) which has led the 
ARIN Board to say: folks, you really oughta seriously consider IPv6 
now. See this link for what they really said:

To summarize what NANOG 40 was really all about, it is about the need 
for more and more network capacity (speed).  It seems that we are 
back to the days of a lot of people wanting to push a lot of content. 
A lot of the overcapacity from the so-called ".COM bubble collapse" 
is nearly used up as the network economy has recovered.

And with that, my travels will slow for a while (thankfully!) until 
the late July IETF 69.  Currently there is an agenda slot for DNSOP 
(DNS Operations) and for ENUM.  I believe this is thought to be the 
last ENUM face-to-face meeting.  The current agenda for that meeting, 
which changes often, has the two meetings on Monday and Tuesday of 
the IETF week.  There is no DNSEXT (DNS Extensions) meeting scheduled.
