 *
 * 2.1.1.  The CSYNC Resource Record Wire Format

 *    The CSYNC RDATA consists of the following fields:
 *
 *                           1 1 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 2 2 3 3

 *      +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
 *
 * 2.1.1.1.  The SOA Serial Field
 *
 *    The SOA Serial field contains a copy of the 32-bit SOA serial number
 *    from the child zone.  If the soaminimum flag is set, parental agents
 *    querying children's authoritative servers MUST NOT act on data from
 *    zones advertising an SOA serial number less than this value.  See
 *    [RFC1982] for properly implementing "less than" logic.  If the
 *    soaminimum flag is not set, parental agents MUST ignore the value in
 *    the SOA Serial field.  Clients can set the field to any value if the
 *    soaminimum flag is unset, such as the number zero.
 *
 * (...)
 *
 * 2.1.1.2.  The Flags Field
 *
 *    The Flags field contains 16 bits of boolean flags that define
 *    operations that affect the processing of the CSYNC record.  The flags
 *    defined in this document are as follows:
 *
 *       0x00 0x01: "immediate"
 *
 *       0x00 0x02: "soaminimum"
 *
 *    The definitions for how the flags are to be used can be found in
 *    Section 3.
 *
 *    The remaining flags are reserved for use by future specifications.
 *    Undefined flags MUST be set to 0 by CSYNC publishers.  Parental
 *    agents MUST NOT process a CSYNC record if it contains a 1 value for a
 *    flag that is unknown to or unsupported by the parental agent.
 *
 * 2.1.1.2.1.  The Type Bit Map Field
 *
 *    The Type Bit Map field indicates the record types to be processed by
 *    the parental agent, according to the procedures in Section 3.  The
 *    Type Bit Map field is encoded in the same way as the Type Bit Map
 *    field of the NSEC record, described in [RFC4034], Section 4.1.2.  If
 *    a bit has been set that a parental agent implementation does not
 *    understand, the parental agent MUST NOT act upon the record.
 *    Specifically, a parental agent must not simply copy the data, and it
 *    must understand the semantics associated with a bit in the Type Bit
 *    Map field that has been set to 1.

 *    follows:
 *
 *                 +0 (MSB)                            +1 (LSB)
 *       +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
 *    0: |                          OPTION-CODE                          |
 *       +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+

 *       +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
 *    4: |                            FAMILY                             |
 *       +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
 *    6: |     SOURCE PREFIX-LENGTH      |     SCOPE PREFIX-LENGTH       |
 *       +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
 *    8: |                           ADDRESS...                          /
 *       +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
 *
 *    o  (Defined in [RFC6891]) OPTION-CODE, 2 octets, for ECS is 8 (0x00
 *       0x08).
 *
 *    o  (Defined in [RFC6891]) OPTION-LENGTH, 2 octets, contains the
 *       length of the payload (everything after OPTION-LENGTH) in octets.
 *
 *    o  FAMILY, 2 octets, indicates the family of the address contained in
 *       the option, using address family codes as assigned by IANA in
 *       Address Family Numbers [Address_Family_Numbers].
 *
 *    The format of the address part depends on the value of FAMILY.  This
 *    document only defines the format for FAMILY 1 (IPv4) and FAMILY 2
 *    (IPv6), which are as follows:
 *
 *    o  SOURCE PREFIX-LENGTH, an unsigned octet representing the leftmost
 *       number of significant bits of ADDRESS to be used for the lookup.
 *       In responses, it mirrors the same value as in the queries.
 *
 *    o  SCOPE PREFIX-LENGTH, an unsigned octet representing the leftmost
 *       number of significant bits of ADDRESS that the response covers.
 *       In queries, it MUST be set to 0.
 *
 *    o  ADDRESS, variable number of octets, contains either an IPv4 or
 *       IPv6 address, depending on FAMILY, which MUST be truncated to the
 *       number of bits indicated by the SOURCE PREFIX-LENGTH field,
 *       padding with 0 bits to pad to the end of the last octet needed.
 *
 *    o  A server receiving an ECS option that uses either too few or too
 *       many ADDRESS octets, or that has non-zero ADDRESS bits set beyond
 *       SOURCE PREFIX-LENGTH, SHOULD return FORMERR to reject the packet,
 *       as a signal to the software developer making the request to fix
 *       their implementation.
 *
 *    All fields are in network byte order ("big-endian", per [RFC1700],
 *    Data Notation).

 * ISDN tests.
 *
 * RFC 1183:
 *
 * 3.2. The ISDN RR
 *
 *    The ISDN RR is defined with mnemonic ISDN and type code 20 (decimal).
 *
 *    An ISDN (Integrated Service Digital Network) number is simply a
 *    telephone number.  The intent of the members of the CCITT is to
 *    upgrade all telephone and data network service to a common service.
 *
 *    The numbering plan (E.163/E.164) is the same as the familiar
 *    international plan for POTS (an un-official acronym, meaning Plain
 *    Old Telephone Service).  In E.166, CCITT says "An E.163/E.164
 *    telephony subscriber may become an ISDN subscriber without a number
 *    change."
 *
 *    ISDN has the following format:
 *
 *    <owner> <ttl> <class> ISDN <ISDN-address> <sa>
 *
 *    The <ISDN-address> field is required; <sa> is optional.
 *
 *    <ISDN-address> identifies the ISDN number of <owner> and DDI (Direct
 *    Dial In) if any, as defined by E.164 [8] and E.163 [7], the ISDN and
 *    PSTN (Public Switched Telephone Network) numbering plan.  E.163
 *    defines the country codes, and E.164 the form of the addresses.  Its
 *    format in master files is a <character-string> syntactically
 *    identical to that used in TXT and HINFO.
 *
 *    <sa> specifies the subaddress (SA).  The format of <sa> in master
 *    files is a <character-string> syntactically identical to that used in
 *    TXT and HINFO.
 *
 *    The format of ISDN is class insensitive.  ISDN RRs cause no
 *    additional section processing.
 *
 *    The <ISDN-address> is a string of characters, normally decimal
 *    digits, beginning with the E.163 country code and ending with the DDI
 *    if any.  Note that ISDN, in Q.931, permits any IA5 character in the
 *    general case.
 *
 *    The <sa> is a string of hexadecimal digits.  For digits 0-9, the
 *    concrete encoding in the Q.931 call setup information element is
 *    identical to BCD.
 *
 *    For example:
 *
 *    Relay.Prime.COM.   IN   ISDN      150862028003217
 *    sh.Prime.COM.      IN   ISDN      150862028003217 004
 *
 *    (Note: "1" is the country code for the North American Integrated
 *    Numbering Area, i.e., the system of "area codes" familiar to people
 *    in those countries.)
 *
 *    The RR data is the ASCII representation of the digits.  It is encoded
 *    as one or two <character-string>s, i.e., count followed by
 *    characters.

 * 4.1.1.  The Next Domain Name Field
 *
 *    The Next Domain field contains the next owner name (in the canonical
 *    ordering of the zone) that has authoritative data or contains a
 *    delegation point NS RRset; see Section 6.1 for an explanation of
 *    canonical ordering.  The value of the Next Domain Name field in the
 *    last NSEC record in the zone is the name of the zone apex (the owner
 *    name of the zone's SOA RR).  This indicates that the owner name of
 *    the NSEC RR is the last name in the canonical ordering of the zone.
 *
 *    A sender MUST NOT use DNS name compression on the Next Domain Name
 *    field when transmitting an NSEC RR.
 *
 *    Owner names of RRsets for which the given zone is not authoritative
 *    (such as glue records) MUST NOT be listed in the Next Domain Name
 *    unless at least one authoritative RRset exists at the same owner
 *    name.
 *
 * 4.1.2.  The Type Bit Maps Field
 *
 *    The Type Bit Maps field identifies the RRset types that exist at the
 *    NSEC RR's owner name.
 *
 *    The RR type space is split into 256 window blocks, each representing
 *    the low-order 8 bits of the 16-bit RR type space.  Each block that
 *    has at least one active RR type is encoded using a single octet
 *    window number (from 0 to 255), a single octet bitmap length (from 1
 *    to 32) indicating the number of octets used for the window block's
 *    bitmap, and up to 32 octets (256 bits) of bitmap.
 *
 *    Blocks are present in the NSEC RR RDATA in increasing numerical
 *    order.
 *
 *       Type Bit Maps Field = ( Window Block # | Bitmap Length | Bitmap )+
 *
 *       where "|" denotes concatenation.
 *
 *    Each bitmap encodes the low-order 8 bits of RR types within the
 *    window block, in network bit order.  The first bit is bit 0.  For
 *    window block 0, bit 1 corresponds to RR type 1 (A), bit 2 corresponds
 *    to RR type 2 (NS), and so forth.  For window block 1, bit 1
 *    corresponds to RR type 257, and bit 2 to RR type 258.  If a bit is
 *    set, it indicates that an RRset of that type is present for the NSEC
 *    RR's owner name.  If a bit is clear, it indicates that no RRset of
 *    that type is present for the NSEC RR's owner name.
 *
 *    Bits representing pseudo-types MUST be clear, as they do not appear
 *    in zone data.  If encountered, they MUST be ignored upon being read.

 *
 * For example, if PROTOCOL=TCP (6), the 26th bit corresponds to TCP port
 * 25 (SMTP).  If this bit is set, a SMTP server should be listening on TCP
 * port 25; if zero, SMTP service is not supported on the specified
 * address.
