2. Can or should there be an alias for chaos to ch like
in BIND's dig?
The CHAOS alias in dig(1) works, but it is not documented in current versions.
Specifically dig(1) says:
| The IN and CH class names overlap with the IN and CH top-level domain names.
| Either use the -t and -c options to specify the type and class, use the -q to
| specify the domain name, or use "IN." and "CH." when looking up
these top-level
| domains.
I wasn't even aware of being able to use "CHAOS"; I don't think I'll
adopt it.
