Fun fact: CH (Chaos) is another DNS class. Today mostly IN (Internet) is used for, well, the internet. Chaos is a leftover from the Chaosnet, a local area network developed at MITs AI lab in 1975.

The Swiss TLD is ch. If you want to query it directly, for example to get the nameservers authoritative for ch. and you forget the canonical dot, dig will interpret "CH" as the Chaos class and return something unexpected.

There is also a third DNS class, HS (Hesiod) which is basically /etc/passwd but served over DNS.
