Methods and devices for detecting an IP address
First Claim
1. A method for detecting an IP address, for application in an access router in an operator'"'"'s network, with said access router being connected via a first interface to a network accessed by a user and being connected via a second interface to an upstream access channel of the operator'"'"'s network, wherein, said access router configures the detected IP address and the method comprises:
- releasing by said access router routes of said detected IP address via said first interface and said second interface, and setting that a priority of the route released via said first interface is lower than that of a route released via said second interface;
after having received by said access router a WEB request by the user via said first interface, searching a session record corresponding to said WEB request;
establishing by said access router the session record corresponding to said WEB request when the corresponding session record is not found, and returning a redirecting message taking said detected IP address as a re-directed destination IP address; and
after having received by said access router via said second interface another message having the re-directed destination IP address, determining that the user who sent said another message is an illegal user.

Abstract
A method for detecting an IP address. An access router releases the routes of a detected IP address via a first interface and a second interface, and sets the priority of the route released via said first interface lower than that of the route released via said second interface. After having received by said access router a WEB request by the user via said first interface, the method comprises searching a session record corresponding to said WEB request; establishing by said access router the session record corresponding to said WEB request when the corresponding session record is not found, and returning a redirecting message taking said detected IP address as the re-directed destination IP address; and after having received by said access router via said second interface the message taking said detected IP address as the destination IP address, determining that the user who sent said message is an illegal user.

6. A device for detecting an IP address, which device acts as an access router for application in an operator'"'"'s network, wherein said device is connectable via a first interface to a network accessed by a user and is connectable via a second interface to an upstream access channel of the operator'"'"'s network, said device comprises:
-
a configuration unit to configure a detected IP address; a route releasing unit to release routes of said detected IP address via said first interface and said second interface, and to set that the priority of the route released via said first interface is lower than that of the route released via said second interface; a receiving unit to receive messages sent by the user via said first interface and second interface; a searching unit to search a session record corresponding to a WEB request when said receiving unit receives via said first interface said WEB request sent by the user; a record establishing unit to establish a session record corresponding to said user when said searching unit fails to find a matched session record; a redirecting unit to return a redirecting message which takes said detected IP address as a re-directed destination IP address when said searching unit fails to find the corresponding session record; and a detecting unit to detect whether a destination IP address of another message received by said receiving unit via said second interface is said detected IP address, and determining that the user who sent said another message is an illegal user when the detection result is yes. - View Dependent Claims (7, 8, 9, 10)
