Record data for OPT records.
Since DNS message headers are relatively short, the amount of information that can be conveyed through them is very limited. In order to provide an extensible means to transmit additional information, RFC 6891 introduces a resource record called OPT that can be added to the additional section of a message. The record data in turn consists of a sequence of options.
This module contains the types for working with both the OPT record and its record data. It defines types for each of the currently defined options. As with record data types in the rdata module, these are arranged in sub-modules according to the RFC that defined them and then re-exported here.
