Problems solved by technology

[0003] In order to facilitate the application, some current network access devices are set to allow PPP and virtual local area network (VLAN) access at the same time; users accessing the Internet through VLAN obtain IP addresses through DHCP, and the IP address pool is managed by the DHCP server; It can be seen from the above-mentioned prior art that users accessing the Internet through PPP do not obtain IP addresses through the Dynamic Host Configuration Protocol (DHCP), and the IP address pool that provides IP addresses for Internet users is not managed by the DHCP server; in this case Just make the IP address allocation of two different Internet users not carry out unified management, the hidden danger of IP address conflict then exists in the non-uniform management of IP address; Network Service Providers' Requirements for Unified Management of Network Resources

Embodiment Construction

[0020] The specific embodiment of the method that the user who gets online through PPP that the present invention provides obtains IP address from DHCP server is described as follows:

[0021] Step 1: the user who surfs the Internet through PPP logs in to the network, and establishes a connection link with the PPP processing module. The PPP processing module is a functional module that completes the PPP protocol service in the network access server, and the user who surfs the Internet through PPP is called a PPP client;

[0022] Step 2: The PPP client sends an authentication request message to the PPP processing module, which carries information such as the user name and password of the user. The authentication request message is used for the user to request to pass the authentication and obtain an IP address to become an Internet user who can access the network. user;

[0023] Step 3: The PPP processing module sends the information such as the expected network segment of the ...

Abstract

A method to obtain Internet protocol address by the User on the network through point to point protocol includes sending internal information message of distributing IP address request to DHCP junction module which simulates out IP address request message in DHCP form for the User as per abovesaid message and to send it to DHCP server which distributes on IP address according to the received content of IP address request message and to give out additional information of the address, informing the IP address and additional information to the user through DHCP junction module. The method can make the User on network through PPP and VLAN obtain IP address through DHCP server.

Description

technical field [0001] The invention relates to a method for Internet users to obtain Internet Protocol (IP) addresses, in particular to a method for Internet users to obtain IP from a Dynamic Host Configuration Protocol (DHCP) server through Point-to-Point Protocol (PPP). Background technique [0002] At present, there are two ways to obtain an IP address for a user accessing the Internet through PPP: one is that the user is assigned an IP address by the access server after passing the authentication; Finally, the RADIUS server gives the user an IP address, or the RADIUS server specifies in the authentication passing message that the network access server allocates an IP address (NAS-Alloc-IP), and then the access server allocates an IP address for the user. The access server manages the IP address resource through the local IP address pool. If the IP address is allocated by the RADIUS server, the IP address resource is managed by the RADIUS server by configuring an address...
