Abstract

The embodiment of the present invention discloses a method and device for a client to access a network, which is applied to a BRAS device. The method includes: sending an authentication request message to an authentication server according to a discovery message sent by the client; receiving the authentication server The authentication acceptance message sent; the authentication acceptance message includes: the IP address of the authorized DNS server; inserting the IP address into the discovery message and sending it to the remote address assignment server; receiving the returned IP address from the remote address assignment server the IP address and send it to the client, so that the client accesses the network according to the IP address. By applying the embodiment of the present invention, the client can use the IP address of the authorized DNS server to access the network.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for a client to access a network. Background technique [0002] BRAS (Broadband Remote Access Server, Broadband Remote Access Server) system has flexible access methods, effective address management functions, powerful user management functions, and can provide rich and flexible business and control functions. For this reason, the client often uses the BRAS device to access the access network. Specifically, the process for the client to use the BRAS device to access the network includes: [0003] The client sends a discovery message to the BRAS device, and then sends an authentication request to the authentication server through the BRAS device for authentication; [0004] After passing the authentication, the authentication server sends the IP (Internet Protocol, Internet Protocol) address of the DNS (Domain Name System, Domain Name System) server expec...
