Abstract
The invention discloses a method of distributing IP addresses in a differentiation mode and a system thereof. When receiving a dialing authentication request sent by a user terminal, a certification authentication subsystem extracts identification information included in the dialing authentication request. The certification authentication subsystem uses the identification information to carry out certification authentication on the user terminal. When the certification authentication is successful, the certification authentication subsystem inquires IP attribute information associated with the identification information. The certification authentication subsystem sends the identification information and the IP attribute information to BRAS. The BRAS sends IP addresses corresponding to the IP attribute information to the user terminal associated with the identification information. Through configuring the IP attribute information of the user terminal, aiming at IP address protocol type and client type information supported by the BRAS, the corresponding IP addresses are distributed so that differentiation distribution of the IP addresses is realized.
