BTW, Iljitsch notes that "he is worried, but not as much as Dean seems to
be". As I told Iljitsch, I'm not saying the sky is falling, but I am
saying there is a problem, and instead of addressing the problem, people
are just making personal attacks.
Responding to Iljitsch and Booloo's comments only, and recognizing that
somehow or other 6 month old threads on other lists seem to have made their
way onto NANOG...

Subject: Re: [dnsop] Re: Root AnycastTroll Bot <dean@av8.com> keeps mentioning PPLB. May be some people
more knowledgeable about BGP than I am will explain to me why PPLB is
such a new issue for anycasting?
<snip>
Now the part that worries me is what's happening in .org. They only use
two addresses in the delegation from the root, and both are heavily
anycasted. This makes no sense at all as it effectively hides all but
two of the .org TLD servers while there are no reasons at all for not
making at least have a dozen others visible.
In October of 2004 this was the case. It has not been the case since early
this year;

The IPv6 instances are awaiting resolution of some technical issues with the
root, but we expect that in the next couple of weeks, tld1.ultradns.net and
tld4.ultradns.org will also have AAAA records. Also anycast.
We're currently doing some lab work to make sure we fully understand the
effects of adding IPv6 records, plus glue, in terms of exceeding udp packet
sizes. But that is grist for another mill, so to speak.
See y'all in Seattle. Daniel Karrenberg and others will be providing loads
of fuel to spark debate amongst non-kooks about the efficacy of anycast DNS
