Errors in RFC 1912: "Common DNS Operational and Configuration Errors"
Okay, I'm human. (my reviewers are more human than I :-) Here's the errors that have
been noticed since publication.
	- All-numeric labels are allowed.  You just can't just have all all-numeric
	labels. (otherwise it could be misparsed as an IP address). Delete the sentence
	on page 2 starting "Note there are some..." where it references 411.org an
	1776.com. [ reported by Bill Fenner ]
 
	- The section on Page 7 regarding CNAME->MX is too strongly worded. While
	historically this is a thing which has been "not done", there's nothing
	technically illegal about it. Note that for some large sites (like AOL) it's
	really the only way to do what they want. (that is have lots and lots of
	delivery addresses) The CNAME is basically a trick so DNS doesn't overfill the
	UDP packet, forcing a second query to get the rest. Rather than saying it's
	illegal, it should simply be "discouraged". [ reported by D. J. Bernstein ]
