Detailed Description

Structure for EDNS client subnet option.

Field Documentation

edns_cs_raw_buf

unsigned char* edns_client_subnet_s::edns_cs_raw_buf

Pointer in request_buffer where EDNS client subnet opt begins.

edns_cs_raw_buf_len

uint16_t edns_client_subnet_s::edns_cs_raw_buf_len

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

edns_cs_valid

bool edns_client_subnet_s::edns_cs_valid

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

family

uint16_t edns_client_subnet_s::family

Client subnet IP family, 1 = IPv4, 2 = IPv6.

ip

struct sockaddr_storage edns_client_subnet_s::ip

Client subnet IP.

scope_mask

uint8_t edns_client_subnet_s::scope_mask

Client subnet scope mask. This is the mask that we are responding for. Set by response, in query it MUST be 0 (RFC 7871).

source_mask

uint8_t edns_client_subnet_s::source_mask

Client subnet source mask. This is the mask requested. Set by query, response mirrors what was in query. (RFC 7871)
