	for "fun" - some folks rotate the various canonical names
	that exist for any given A or AAAA or (for difficult types)
	A6 records that exist.

	and Jim, you confuse me.  

posit:

twinkle.little.bat.	AAAA	3ffe::dead:beef
muffet.satona.tuffit.	aaaa	3ffe::dead:beef
PDC.e164.arpa.		AAAA	3ffe::dead:beef

	which is THE canonical lable for the address 3ffe::dead:beef ??
