Problems solved by technology

Because these solutions require a large amount of assembly of the entire network, the cooperation between ISPs, and the possibility of improving the routing equipment with a huge stock in the existing network, the research progress and application promotion are not smooth.

Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings.

[0042] The present invention proposes an IP network traceability method, sets a traceability log, and associates a unique terminal identifier with an IP address of the terminal, and records the corresponding relationship in the traceability log.

[0043] For users of different access modes, the present invention may have different embodiments.

[0044] For users with static IP addresses, the method of the preferred embodiment of the present invention is specifically:

[0045] Step 1, set up the traceability log, and correspond the unique identifier of the terminal to the IP address of the terminal, and record the corresponding relationship in the traceability log, wherein the unique identifier of the terminal can be the MAC address of the network card of the terminal;

[0046] Step 2, setting an ACL (Access Control List, access control list), the ACL only allows the d...

Abstract

The invention provides an IP network tracing method and an IP network tracing system. The method comprises the steps of judging whether an IP address in a tracing request belongs to a database of a hierarchical address recording module or not; if yes, judging whether the IP address belongs to a source domain of the hierarchical address recording module; if yes, searching the recording of the IP address in the trace log of the source domain. The system comprises a search module, a tracing interface module, a hierarchical address recording module and a trace log module. Through the establishment of the hierarchical address management filing system, a domain for which an IP address is dedicated for can be quickly found out through the query mechanism by means of corresponding log information recorded in a boundary apparatus of the source domain. Thus, the efficient traceability of Internet IP addresses is realized.

Description

technical field [0001] The present invention relates to an IP network technology, in particular to a method and system for network traceability of an IP network. Background technique [0002] Due to the fast and convenient data packet addressing and transmission mode of the IP (Internet Protocol, a protocol for interconnection between networks), more and more networks choose to use the TCP / IP protocol. [0003] The TCP / IP protocol only checks the destination address when forwarding the data packet, and forwards the data packet according to the destination address of the data packet, but does not check the source IP address. This can quickly transmit data packets and reduce system load, but it also gives opportunities for data packets to disguise their own source IP addresses, so the TCP / IP protocol has very low traceability to the network. [0004] With the popularity of the Internet, cybercrime is becoming more and more rampant. The lack of Internet traceability has led t...
