Greetings again. In a definitely non-exhaustive survey, it appears that F, H, K, and L respond to the EDN0 NSID (RFC 5001) query.
1) Are there others that do so, at least on some of their hosts?
I think at least I does.
Ah, I see that now from a different location.
2) Are there rootops who do per-host identification in some other way?
I seem to remember that K answers the usual CHAOS hostname.bind queries, other might do as well. And vaguely remembers others to do so.
It doesn't seem to be interesting if a rootop does both the standard way (NSID) and some non-standard way. It would be interesting if a rootop only does it in a non-standard way.
The following paper looked at using CHAOS queries and other techniques (traceroute, etc.) to locate anycast instances: Xun Fan, John Heidemann, and Ramesh Govindan. Evaluating Anycast in the Domain Name System. In _Proceedings of the IEEE Infocom_. Turin, Italy, IEEE. April, 2013. <http://www.isi.edu/~johnh/PAPERS/Fan13a.html>. I went back to look about rfc5001---the paper says "RFC-5001 is not yet widely supported". The work in the paper ran 2011 to 2012, FWIW.
3) Is this an appropriate topic for the RSSAC Caucus?
I'm not sure where you hint at. Is there something to discuss here?
I'm not hinting at anything; I am really wondering if this is an appropriate topic for the Caucus. If people here find identification important for rootops to do, the Caucus can put together a recommendation. If people here don't find it important, than there's no need for discussion.
The topic is about DNS and so is relevant, but... about "put together a recommendation": A recommendation about what, exactly? Framing some problem (even if that framing evolves) seems important before embarking on some course of activity. -John Heidemann
