Hierarchical IPv6 Domain Name Configuration via Network Access Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current domain name configuration methods in IPv6 networks are inadequate for large-scale management, particularly in home networks, as they lack secure and manageable registration processes, and require individual device installation of DDNS client software, making it difficult to manage and access devices remotely.
Innovation Solution
A method and device for hierarchical domain name configuration in IPv6 networks, involving authentication, DHCP, and DNS registration units that negotiate a unique user network name, obtain and form a unique suffix for domain names, and automatically configure resource records on the network provider's DNS server, enabling secure and unified management of domain names across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If DDNS client software is installed on each device for automatic domain name registration, then automatic domain name configuration is achieved, but device complexity and management difficulty increase
Solution Approach 1:
The patent extracts the DDNS client software requirement from individual devices and consolidates the domain name registration function into the network access device (DSLAM/BRAS). This allows devices to receive domain name information automatically through DHCP without installing additional software, thereby achieving automation while reducing device complexity.
Solution Approach 2:
The network access device serves as an intermediary between devices and the DNS server. It receives domain name information from the operator and automatically configures DNS records without requiring devices to perform authentication or installation operations, thus simplifying the overall system architecture.
2Measurement precision
If manual domain name configuration is used, then control precision is improved, but configuration time and operational complexity increase
Solution Approach 1:
The operator pre-configures domain name information and pricing policies in the network access device before user connection. When a user connects, the system automatically retrieves and applies the pre-configured domain name information through DHCP, eliminating manual configuration time while maintaining precise control over domain name assignment.
Solution Approach 2:
The system provides self-service domain name configuration where users automatically receive domain name information through standard DHCP processes without operator intervention. The network access device autonomously manages domain name registration and configuration, reducing operational time while maintaining configuration precision.
3Ease of operation
If hierarchical domain name management is implemented, then manageability is improved, but system complexity increases
Solution Approach 1:
The patent segments the domain name management function into hierarchical levels: operator-level DNS servers manage root domain names, while network access devices manage local domain name registration. This segmentation allows centralized control for major domains while enabling automated local registration, improving manageability without significantly increasing overall system complexity.
Solution Approach 2:
The network access device performs multiple functions including DHCP service, domain name registration, and DNS record configuration through a single integrated mechanism. This multi-functionality simplifies the system architecture by consolidating what would otherwise require separate systems, thereby improving ease of operation without proportionally increasing complexity.

AI summary
The present invention provides a method and device for hierarchical configuration of domain name in IPv6 network. Said method comprises: a) negotiating a unique user network's name between a user and a network SP; b) a client terminal device at the user network side obtaining prefix of IPv6 network address and suffix of the user network's domain name by sessioning with a network access device, said suffix of the user network's domain name being consisting of the user network's name and suffix of the network SP's domain name; c) the network access device further informing the network SP's DNS server of establishing the resource record of said user network's domain name server; d) said client terminal device conducting the address configuration and providing domain name service for hosts at the user network side according to the obtained prefix of IPv6 network address and suffix of the user network's domain name.
