Hello,

 > Please review current verion.

I have two data points to back some of your claims:

"EDNS0 is now widely deployed"

* We have some data to back this claim up -- but only from a ccTLD 
authoritative DNS vantage point. In short: 90% of the queries .nl sees 
have EDNS0. See data in [0].(if that helps)

   "and DNS (over UDP) is said to be the biggest user of IP fragmentation."

It would be nice to have some ref for that (but I don't one).

 From the .nl servers, we see ~10k fragmented queries from 2.2B daily. 
Sec 3.2 in [1].

thanks,

/giovane
