[UA-discuss] ODG: Re: UA issue

[Mark Svancarek]

I don't think we need to determine which fall into this category a priori, I'm just making sure there are no undefined cells in the matrix.  The verbiage would be used as in this example:

"Regardless whether validation was performed after the email address was accepted in the UI, a service may need to send a test message to the email address to determine if it is *active* or not, thus avoiding assignment and maintenance of accounts attached to *unused* addresses."

How would we determine that?  There are millions of zones on the Internet, and even if you managed to crawl all the public zones you'd still miss stuff because of internal-to-some-network views.

Note that several different uses of the DNS conflict, too.  For example, both Active Directory and Apple's Bonjour over wide area (that is, DNS-SD) use labels that are not compatible with IDNA2008.
That's a mighty big installed base.
