4.1. NSEC RDATA Wire Format
The RDATA of the NSEC RR is as shown below:
1 1 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 2 2 3 3
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

4.1.3. Inclusion of Wildcard Names in NSEC RDATA
If a wildcard owner name appears in a zone, the wildcard label ("*")
is treated as a literal symbol and is treated the same as any other
owner name for the purposes of generating NSEC RRs. Wildcard owner
names appear in the Next Domain Name field without any wildcard
expansion. [RFC4035] describes the impact of wildcards on
authenticated denial of existence.

RFC 4034, DNSSEC Resource Records, March 2005
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.

RFC 4034, DNSSEC Resource Records, March 2005
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.
A zone MUST NOT include an NSEC RR for any domain name that only
holds glue records.
