Re: OPT == type 41?

[marka@isc.org]

	Having a small "cachable" / "non cachable" ranges declared
	in the type space would allow servers to know whether to
	cache or not answers for RR type that it doesn't know within
	these ranges.  When the ranges are close to being filled
	we can declare a new range in addition to the ones already
	declared.

		0 non-cachable.
		1-40 cachable.
		41 non-cachable.
		42-127 cachable.
		128-255 non-cachable.
		256-65535 reserved.

	As for OPT it can stay as an exception, as should 0.
