Re: [DNSOP] [Ext] draft-schanzen-gns and draft-ietf-dns-alt-tld

["Schanzenbach, Martin" <[e-mail]>]

Having now read further I am pretty convinced that the advisory is not useful in the context of this thread discussion.
Ist sais at the end that [1] was the "impetus" for the advisory.
However, [1] states that

"Why not use .alt?
   The proposed .alt presudo-TLD is specifically only for use as a
   pseudo-TLD for non-DNS resolution contexts.  At one point .alt was
   being considered both for DNS and non-DNS resolution contexts, but,
   after much discussion it was decided that the DNSSEC implications
   (and desired behavior) meant that .alt should be reserved
   specifically for non-DNS resolution."

and

"
Why not use something.arpa?
   This is indeed an interesting idea.  I suspect that it fails the
   semantically desirable / understandable case, but is definitely worth
   further discussion.  It may also cause issues when server operators
   override part of the .arpa domain in order to instantiate
   something.arpa.
"

So, I am pretty sure we are back to square one and this advisory (or rather its result) is specifically NOT meant for systems like GNS.
In fact, I would even argue that the advisory itself argues that this work is supposed to be done by IETF (see page 5 of the document):
"
In this document, the SSAC limits its discussion to private-use TLDs intended for use with the DNS protocol and for private use only. Many private-use TLDs, such as .onion and .gnu, do not use the DNS protocol or DNS infrastructure. The reservation and usage for such TLDs would require special handling and is not discussed in this document; there have been efforts in the IETF to address them.
"

While I must admit that I am a bit ignorant when it comes to what is considered official ICANN position, at least the authors of this advisory seem to think that private TLDs not meant for DNS resolution should be/can be/are(!) worked on by the IETF.

I don't think any of us involved then cared whether it was alt or one of thousands of other strings that it could have been.  The main point was to come up with something that would not pad total length too much and that could be a clear "protocol switch".  The registration in the IANA sutld registry was suppossed to ensure the same outcome as what is going through SSAC, but it makes no difference to me what the characters are.  Note that because of the old-timey restriction, I suspect the characters must all be alphabetic, though perhaps that rule has been superseded by IDNA.
