Embodiment Construction
[0022] Embodiments of the present invention provide a method, device and content distribution network server for blocking an IP address, which can solve the problems of long processing time and low efficiency when blocking an IP address in the prior art.
[0023] Embodiments of the present invention provide a method for banning IP addresses, such as figure 2 shown, including the following steps:
[0024] S201: Receive the request message sent by the client, after the request message enters the network layer, first determine the source IP address of the request message;
[0025] S202: Search the stored blacklist, and discard the request message when it is determined that the source IP address belongs to the blacklist.
[0026] Preferably, in order to improve search efficiency, all IP addresses stored in the blacklist are stored according to preset storage rules; the searching of the saved blacklist is specifically: searching for the blacklist according to the storage rules L...

The invention discloses a method and a device for banning IP (Internet Protocol) addresses and a content distribution network server. The method comprises the following steps: receiving a request message sent by a client side, and firstly conforming a resource IP address of the request message when the request message enters a network layer; and looking up a stored blacklist, and abandoning the request message when the IP address belongs to the blacklist. With the method and the device for banning IP addresses, whether the request message is required to be banned is begun to be ensured when the request message enters the network layer, the request message is not required to be subsequently processed in other layers, and more over, other conventional processing processes in the network layer are also not required, so that the searching efficiency can be improved, the processing time for banning the IP addresses is reduced, and the processing efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a method, a device and a content distribution network server for blocking IP addresses in a network. Background technique [0002] At present, servers in the network, based on security considerations, must adopt certain methods to filter some request messages that do not need to be responded to. A common method of filtering is to block the source IP addresses of relevant request messages. [0003] In the ISO / OSI seven-layer network architecture, a request message arriving at the server usually needs to be processed by each protocol layer sequentially from bottom to top. Therefore, the specified source IP can be blocked at multiple protocol layers of the OSI. A common processing method is to block the specified source IP at the application layer or the network layer. [0004] Taking the CDN network as an example, in the CDN network implemented based on squid, the source IP...
