Jan Včelák submitted a GitHub issue about loop detection which I think
should be discussed by the wg not just the authors.
https://github.com/each/draft-aname/issues/45
The -02 draft requires that CNAME+ANAME chains are chased to their
ultimate target. There are a few reasons for this:
* It is more CNAME-like (though the draft doesn't amend CNAME's behaviour
to chase ANAMEs.)
* It reduces the amount of TTL stretching that can occur if there is an
ANAME chain.
If these requirements are relaxed then it makes sense to chase chains less
enthusiastically.
WRT loop detection, it is much easier if the additional section in the
response from the resolver contains the chain(s). The draft doesn't
specify that at the moment; maybe it should.
Tony.

later in west. Thundery wintry showers. Good, occasionally poor.
