[0072] In the embodiment of the present application, the client sends the first message to find the first server, the first server can receive the first message, and thus responds to the second message. Based on this, the client receives the second message sent by the first server.

[0073] It should be noted that, in the embodiment of the present application, as described in the above step S101, the first message can be a Discover message, and the first server to be found is a DHCP server. In this scenario, referring to Figure 2 , the second message can be an Offer message. In addition, the first message can be a Solicit message, and the first server to be found is a DHCPv6 server. In this scenario, referring to Figure 4 , the second message can be an Advertise message. The specific second message is not limited in the embodiments of the present application.

[0074] In the embodiment of the present application, the second message carries a newly added first option (Option) including: a service type of the client, a service identifier allocated according to the service type, and an allocation mode of the service identifier. If the first server is a DHCP server, the first option is specifically a DHCP Option. If the first server is a DHCPv6 server, the first option is specifically a DHCPv6 Option. Referring to the format of the first option shown in Figure 2 , it further includes Option_ServiceID, which is an option identifier reserved for the first server and not occupied, Option-Len, which is an option length, Func-Type, which indicates the allocation mode of the service identifier, Func-Len, which indicates the length of the service identifier, Service-Type, which indicates the service type, ServiceID, which indicates the service identifier allocated according to the service type, Preferred-lifetime, which indicates the preferred lifetime, and Valid-lifetime, which indicates the valid time length.
