The disclosure proposes a domain name system parameter selection method and a related device, which relate to the technical field of network communication. The terminal device in the IPv6 network receives domain name system configuration packets sent by at least two external devices, and the domain name system configuration packets include domain name server addresses and the priority of pre-configured domain name server addresses or include domain name suffixes and pre-configured domain name suffixes The priority of the domain name server address, the terminal device can determine the selection order of the domain name server address in the domain name system configuration message sent by the at least two external devices according to the priority order of the at least two domain name server addresses, according to the at least two domain name suffixes The priority order can determine the selection order of the domain name suffixes in the domain name system configuration messages sent by the at least two external devices, so as to select a suitable domain name server address or domain name suffix.
Description
technical field [0001] The present disclosure relates to the technical field of network communication, in particular, to a domain name system parameter selection method and a related device. Background technique [0002] In an IPv6 (Internet Protocol Version 6, Internet Protocol version 6) network, the DNS (Domain Name System, Domain Name System) information carried in the DHCP message sent by the host through the Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol, DHCP) server Alternatively, the domain name suffix and the address of the domain name server providing the domain name resolution service may be obtained through the DNS information carried in the RA (Router Advertisement, Router Advertisement) message sent by the gateway device. When multiple gateway devices and multiple DHCP servers exist in the IPv6 network and all provide domain name server addresses and domain name suffixes to the host, the host cannot determine the selection order of th...
