IPv6 Domain Validation via Proxy in IPv4 Certificate Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current validation systems do not support IPv6 addressing, necessitating a need to validate IPv6 addresses as part of the transition to IPv6 addressing for issuing digital certificates, particularly in IPv4 networks.
Innovation Solution
A proxy server is used externally to the validation server in an IPv4 network to connect with IPv6 addresses, making requests and returning validation results to the validation server, enabling it to perform validation checks on IPv6 domains within an IPv4 infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a validation server operates within an IPv4 address space, then it can maintain existing IPv4 infrastructure and protocols, but it cannot directly validate IPv6 addresses
Solution Approach 1:
The patent introduces a proxy server as an intermediary component between the IPv4-based validation server and the IPv6 address space. The proxy server receives validation requests from the validation server, translates them into IPv6-compatible requests, performs the validation, and returns results. This intermediary approach allows the validation server to validate IPv6 addresses without requiring direct IPv6 support, resolving the contradiction by adding adaptability while maintaining the existing IPv4 infrastructure.
2Productivity
If manual validation processes are used for IPv6 addresses, then validation accuracy can be maintained, but resource consumption and time requirements increase
Solution Approach 1:
The patent implements an automated validation system where the proxy server autonomously performs IPv6 address validation by executing HTTP GET requests to the target addresses. The system self-manages the validation process without requiring manual intervention, automatically interpreting response status codes (e.g., 200 for successful validation) and returning results to the validation server. This automation increases productivity while the efficient HTTP-based approach keeps resource consumption manageable.

AI summary
Systems and methods are described herein for validating an Internet Protocol (IP) version 6 (IPv6) address from an IP version 4 (IPv4) network. A method, according to one implementation, includes a step of receiving an IPv4-based request from a validation server that is configured to support an IPv4 address space. The method further includes a step of sending an IPv6-based request to a domain supporting an IPv6 address space. Also, the method includes receiving a response status code and domain validation information from the domain. Then, the method includes a step of passing the response status code and domain validation information to the validation server.
