IPv4 to IPv6 Packet Translation for Address Conflict Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data packet routing techniques face addressing conflicts due to overlapping IP addresses in networks, which are costly to resolve, especially for low-cost mobile devices.
Innovation Solution
Translating data packets from IPv4 to IPv6 format by adding prefixes to source and destination addresses, allowing them to be distinctly identifiable and routed through IPv6 networks, and then translating them back to IPv4 for delivery, thereby mitigating addressing conflicts.

Engineering Contradiction Analysis
1Adaptability or versatility
If IPv4 address space is used for networking, then device connectivity is achieved, but addressing conflicts occur due to overlapping IP addresses in different networks
Solution Approach 1:
The patent applies dimensionality change by transitioning from 32-bit IPv4 addressing to 128-bit IPv6 addressing. This expands the address space from approximately 4 billion addresses to over 340 undecillion addresses, effectively eliminating addressing conflicts while maintaining device connectivity. The IPv6 address structure provides sufficient unique addresses for every device on every planet for thousands of years, resolving the fundamental limitation of IPv4 address exhaustion and overlapping address spaces.
2Reliability
If IPv6 format is used for data packet routing, then addressing conflicts are eliminated, but compatibility with existing IPv4 infrastructure is reduced
Solution Approach 1:
The patent employs an intermediary approach by introducing translation devices that convert between IPv4 and IPv6 formats. These translation devices act as mediators, allowing IPv6 packets to traverse through IPv4 networks and vice versa. This enables the network to simultaneously support both IPv6 addressing (eliminating conflicts) and existing IPv4 infrastructure (maintaining compatibility), effectively bridging the transition between the two protocols without requiring complete infrastructure replacement.
3Reliability
If translation devices are deployed for IPv4 to IPv6 conversion, then addressing conflicts are mitigated, but device complexity increases
Solution Approach 1:
The patent applies the copying principle by creating virtual representations of translation capabilities within software and firmware layers. Rather than requiring complex hardware translation devices, the invention implements translation functions through software copies of the translation logic, which can run on standard computing devices. This significantly reduces device complexity while maintaining the ability to translate between IPv4 and IPv6 formats, making the solution more deployable and cost-effective.

AI summary
Among other things, one or more techniques and/or system are provided for routing a data packet. Because the data packet may correspond to a source device having an address on a first network that may be similar to an address of a second device on a second network, the data packet may be translated to create a transformed data packet that may be distinguishable from data packets of the second device. For example, the data packet may be translated from a first address format, such as IPv4, to a second address format, such as IPv6, to create a transformed data packet. The transformed data packet may comprise a prefix that may distinctly identify the source device during routing. In this way, the transformed data packet may be identifiable as corresponding to the source device during routing through a network to a destination device.
