IPV6 address conversion method and device based on address pool offset, equipment and medium

Abstract

The invention relates to an IPV6 address conversion method and device based on address pool offset, equipment and a medium, and the method comprises the steps: obtaining an address conversion request; wherein the address translation request comprises an address to be translated, and obtaining an address translation strategy matched with the address to be translated; wherein the address conversion strategy comprises a pre-conversion address object and a post-conversion address object, determining an offset based on an address type of the pre-conversion address object, an address to be converted and an address pool of the pre-conversion address object, and determining a target conversion address based on an address type of the post-conversion address object, the offset and the address pool of the post-conversion address object. Therefore, conversion between different address types is supported, the application range is wide, the converted address can be configured in the address conversion strategy, the converted address does not need to be calculated, and maintenance and management of the IPv6 network are more convenient.

Description

technical field [0001] The present disclosure relates to the technical field of security services, and in particular, to a method, apparatus, device and medium for IPV6 address translation based on address pool offset. Background technique [0002] IPv6 is a complete solution to the problem of IP address shortage. With the continuous expansion of network users, IPv6 is used more and more widely, and the demand for IPv6 network control and management is also increasing. NAT (Network Address Translation) technology not only alleviates the shortage of IP addresses, but also hides and protects computers inside the network, effectively avoiding attacks from outside the network. Combining NAT and IPv6 can effectively reduce the maintenance and management cost of IPv6 network and reduce hacker attacks. [0003] In the related art, the IPv6 address is converted by replacing the address prefix in the IPv6 address and modifying the following 16 bits to ensure that the checksum remain...

AI Technical Summary

Problems solved by technology

However, since the checksum is guaranteed to remain unchanged, the user is not aware of the converted source address and the converted destination address. When using destination conversion, it is necessary to use a conversion tool to calculate the converted real destination address. Address configuration IP (Internet Protocol, Internet Interconnection Protocol), resulting in an increase in the cost of IPv6 network maintenance and management

In addition, only source conversion and destination conversion are supported, and due to algorithm limitations, only subnet addresses can be converted, and the length of the subnet prefix before and after conversion is required to be equal and must be between 16-112, which greatly limits the applicable scenarios
