At the moment the only reason is an expected packet size larger than 512 bytes, but for instance dnssec would be a good reason too. packet: the packet to check Returns true if packet needs edns rr ldns_pkt_edns_udp_size() return the packet's edns udp size packet: the packet Returns the size ldns_pkt_edns_extended_rcode() return the packet's edns extended rcode packet: the packet Returns the rcode ldns_pkt_edns_version() return the packet's edns version packet: the packet Returns the version ldns_pkt_set_edns_udp_size() Set the packet's edns udp size packet: the packet s: the size ldns_pkt_set_edns_extended_rcode() Set the packet's edns extended rcode packet: the packet c: the code ldns_pkt_set_edns_version() Set the packet's edns version packet: the packet v: the version ldns_pkt_set_edns_z() Set the packet's edns z value packet: the packet z: the value ldns_pkt_set_edns_data() Set the packet's EDNS data packet: the packet data: the data AUTHOR The ldns team at NLnet Labs.
