Address conversion method and device, and address tracing method and device

Abstract

The invention provides an address conversion method, an address conversion device, an address tracing method, an address tracing device, an address conversion tracing method and an address conversion tracing system in a network in which different protocols coexist. The address conversion method in the network in which different network protocols coexist is characterized in that the network protocols at least comprise a first network protocol and a second network protocol, and the address conversion method comprises: a fixed mapping relation forming step, which is implemented by forming a fixed mapping relation between a first network protocol address and a first network protocol port number and between a second network protocol address and a second network protocol port number; and an address conversion step, which is implemented by converting the requested first network protocol address into the second network protocol address by using the fixed mapping relation formed in the fixed mapping relation forming step.

Description

technical field [0001] The present disclosure relates to an address translation method, an address translation device, an address traceability method, an address traceability device, an address translation traceability method, and an address translation traceability system in a network where different protocols coexist. More specifically, the present disclosure relates to a network technology and An address translation method, an address translation device, an address traceability method, an address traceability device, an address translation traceability method, and an address translation traceability system in a coexistence network of different network protocols in the security field. Background technique [0002] At present, the rapid development of the Internet industry has brought great changes to people's lives. The protocol IPv4, which is the cornerstone of today's Internet technology, is well known. The so-called IPv4 is the fourth version of the Internet Protocol (...

AI Technical Summary

Problems solved by technology

[0006] Many-to-one mapping of ports can solve the problem of insufficient IPv4 common address resources

In addition, there is a method for converting multiple private IPv4 addresses into public IPv4 addresses to solve the problem of insufficient IPv4 public addresses, but it is not suitable for address translation scenarios in IPv6 and IPv4 coexistence networks
