Routing Domain Identifier for Duplicate Private IP Address Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In complex network environments, particularly cloud-based virtual networks, duplicate private IP addresses can cause management challenges due to difficulty in distinguishing and preserving multiple IP addresses with the same value, leading to communication issues and increased computing resource consumption.
Innovation Solution
A processor-based method that uses routing domain information to identify and merge duplicate private IP addresses by determining attributes such as routing domain identifiers or domain names, allowing for efficient distinction and management of IP addresses across on-premises and cloud environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If private IP addresses are assigned in different network environments (on-premises and cloud), then network flexibility and deployment versatility are improved, but duplicate IP addresses occur causing management difficulties
Solution Approach 1:
The patent segments the routing domain into multiple isolated contexts (on-premises routing domain and cloud routing domain), each with its own routing domain identifier. This segmentation allows duplicate IP addresses to coexist in different segments without conflict, resolving the management complexity while maintaining network environment adaptability.
Solution Approach 2:
The patent introduces a routing domain identifier as an intermediary attribute that mediates between the IP address and the network environment. This intermediary provides the necessary context to distinguish duplicate IP addresses, enabling proper routing decisions without requiring changes to the IP addressing scheme itself.
2Adaptability or versatility
If duplicate private IP addresses are allowed in different routing domains, then network deployment flexibility is improved, but communication reliability deteriorates due to routing conflicts
Solution Approach 1:
The patent adds another dimension (routing domain identifier) to the IP addressing space. This dimensional extension transforms the problem from a one-dimensional IP address conflict into a multi-dimensional space where duplicate IP addresses can be distinguished by their routing domain context, ensuring reliable communication while maintaining deployment flexibility.
Solution Approach 2:
The patent changes the parameter set used for IP address identification by adding the routing domain identifier parameter. This parameter change enables the system to distinguish between duplicate IP addresses in different contexts, resolving routing conflicts and ensuring communication reliability across diverse network environments.
3Measurement precision
If routing domain information is added to distinguish duplicate IP addresses, then IP address management accuracy is improved, but data processing complexity increases
Solution Approach 1:
The patent performs preliminary action by assigning routing domain identifiers to routing domains before IP address allocation. This pre-establishment of routing context allows the system to accurately identify and manage duplicate IP addresses without requiring complex real-time analysis, thus improving identification accuracy while minimizing additional processing complexity.

AI summary
According to examples, an apparatus may include a processor and a memory on which are stored machine-readable instructions that when executed by the processor cause the processor to receive a first IP address using a type of a discovery process for discovery of network configuration information. The processor may determine whether the first IP address is a private IP address or a public IP address. The processor may determine a second attribute of the first IP address, which may include information on a routing domain for the first IP address based on the type of the discovery process used for discovery of the network configuration information. The processor may merge the first IP address with a second IP address based on the second attribute of the first IP address, in which the second IP address may be replaced with the first IP address.
