RFC 1034 has:
Similarly we might see:
XX.LCS.MIT.EDU. IN A 10.0.0.44
CH A MIT.EDU. 2420
Which breaks the rule of a zone being all of one class as the owner
name here is clearly inherited.
A may have been better subtyped but that is water under the bridge now.
XX.LCS.MIT.EDU. IN A IN 10.0.0.44
IN A CH MIT.EDU. 2420
IN A IN6 2001:0DB8::2c
