+ * 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

+ * / Type Bit Map (continued) /
+ * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ *
+ * 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.

+ *
+ * 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

+ *
+ * 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.

+ *
+ * ADDRESS An 32 bit Internet address
+ *
+ * PROTOCOL An 8 bit IP protocol number
+ *
+ * <BIT MAP> A variable length bit map. The bit map must be a
+ * multiple of 8 bits long.
+ *
+ * The WKS record is used to describe the well known services supported by
+ * a particular protocol on a particular internet address. The PROTOCOL
+ * field specifies an IP protocol number, and the bit map has one bit per
+ * port of the specified protocol. The first bit corresponds to port 0,
+ * the second to port 1, etc. If the bit map does not include a bit for a
+ * protocol of interest, that bit is assumed zero. The appropriate values
+ * and mnemonics for ports and protocols are specified in [RFC-1010].
+ *
+ * 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.
