21 DNS packet
22 This structure contains a complete DNS packet (either a query or
24 an answer)
25 It is the complete representation of what you actually send to a
27 nameserver, and what it sends back (assuming you are the client
28 here).

31 Header section:
32 ldns_hdr *_header;
33 /* extra items needed in a packet */
34 The size of the wire format of the packet in octets:
35 ldns_rdf *_answerfrom;
36 Timestamp of the time the packet was sent or created:
37 struct timeval timestamp;
38 The duration of the query this packet is an answer to:
39 uint32_t _querytime;
40 The size of the wire format of the packet in octets:
41 size_t _size;
42 Optional tsig rr:
43 ldns_rr *_tsig_rr;
