DNS resource class numbers

Description

The 16-bit CLASS field of a DNS resource record. In modern practice essentially everything uses IN (Internet); the other registered values (CHAOS, HESIOD, NONE, ANYCLASS) are historic or have specialised uses. See the IANA DNS Classes registry for the full list.

Synopsis

newtype RRCLASS where
- RRCLASS Word16
- pattern ANYCLASS :: RRCLASS
- pattern CHAOS :: RRCLASS
- pattern CS :: RRCLASS
- pattern HESIOD :: RRCLASS
- pattern IN :: RRCLASS
- pattern NONE :: RRCLASS
