DNS_NSEC_DATA structure

The DNS_NSEC_DATA structure represents an NSEC resource record (RR) as specified in section 4 of RFC 4034.

Syntax


typedef struct _DNS_NSEC_DATA {
  PWSTR pNextDomainName;
  WORD  wTypeBitMapsLength;
  WORD  wPad;
  BYTE  TypeBitMaps[1];
} DNS_NSEC_DATA, *PDNS_NSEC_DATA;

Members

pNextDomainName

A pointer to a string that represents the authoritative owner name of the next domain in the canonical ordering of the zone as specified in section 4.1.1 of RFC 4034.

wTypeBitMapsLength

The length, in bytes, of TypeBitMaps.

wPad

Reserved. Do not use.

TypeBitMaps

A BYTE array that contains a bitmap that specifies which RR types are supported by the NSEC RR owner. Each bit in the array corresponds to a DNS Record Type as defined in section in section 4.1.2 of RFC 4034.

Remarks

The DNS_NSEC_DATA structure is used in conjunction with the DNS_RECORD structure to programmatically manage DNS entries.
