Field Documentation

client_subnet

edns_client_subnet_t edns_s::client_subnet

EDNS client subnet

dnssec

bool edns_s::dnssec

DNSSEC supported (DO bit set).

edns_raw_buf

unsigned char* edns_s::edns_raw_buf

Pointer in request_buffere where EDNS rr begins.

edns_raw_buf_len

uint16_t edns_s::edns_raw_buf_len

Length of data in raw buffer for EDNS rr. A length of 0 means that EDNS rr is not present in query request.

edns_valid

bool edns_s::edns_valid

Flag to indicate if EDNS is present & valid (should be used when forming a response).

extended_rcode

uint8_t edns_s::extended_rcode

Extended response code, upper 8 bits.

udp_resp_len

uint16_t edns_s::udp_resp_len

EDNS advertized client supported UDP response length

version

uint8_t edns_s::version

EDNS version. The only supported versin is 0.
