/* Placed in the public domain 2002 by Sam Trenholme */

/* This file describes compression RRs.  The format is as follows:

   rr_number: The number this RR has in a DNS packet
   compression_format: A forwat which tells us the format of
   an RR; A ";" is a delimiter; and the following descriptions
   of data are supported:

  1: This describes a number represented by a single octet

  2: This represents numerical data represented by two octets in
     big-endian format

  4: This represents numerical data represented by four octets in
     big-endian or dotted-decimal format

  D: This represents a domain name label

  T: This represents a text record; a single octet indicating the
     length of a string followed by the string in question

  V: This represents variable-length data not to be parsed; this can
     only be the last or only atom in an RR.


/* The format of this data is described in detail in the
   "describing_dns_rrs" document;
   Basically: rr_number|rr_description|to_compress|text_description;

#define RR_COUNT 17

/* These are deliberately out of order so that common RRs are
   first in the list to speed up lookups */
