Resource Record Types.

Each resource records has a 16 bit type value indicating what kind of information is represented by the record. Normal query includes the type of record information is requested for. A few aditional types, called query types, are defined as well and can only be used in questions. This type represents both these types.

Record types are defined in RFC 1035. The registry of currently assigned values can be found at http://www.iana.org/assignments/dns-parameters/dns-parameters.xhtml#dns-parameters-4

In order to avoid confusion over capitalization, the mnemonics are treated as single acronyms and therefore all variant names are spelled with an initial capital letter in accordance with Rust naming guidelines.
