Eszett and IDNAv2 vs IDNA2008

We would only need a single transaction. Let's take the example
straße, which means "street" in German. IDNA2003 maps this to strasse,
but if you Punycode it directly, you get strae-oqa. I used the "dig"
command to get details of your domain, and then edited the output:

;      IN  A


;; AUTHORITY SECTION:   300 IN  NS   300 IN  NS   300 IN  NS

As I said, there may well be some good reasons not to do this. I'm
sure DNS experts could come up with some reasons.
