Network Device IP Address Redirection for DHCP Reconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The dynamic assignment of IP addresses by DHCP leads to complexities in network configuration, requiring users and administrators to manually redirect IP addresses, making the process cumbersome and not user-friendly, especially upon reconnection.
Innovation Solution
An information process device that detects network connections, acquires and re-acquires IP addresses, and redirects connection requests based on association information, using modules like electric appliance detecting, IP address acquiring, and connection request redirecting, with identifiers such as MAC addresses or unique IDs, to facilitate easy and user-friendly network configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If DHCP automatically assigns IP addresses to electric appliances, then IP address assignment becomes automated and efficient, but the IP address changes after a certain period or upon reconnection, requiring manual redirection by users and administrators
Solution Approach 1:
The system establishes bidirectional communication between the information process device and electric appliances. The device detects appliance connections, monitors IP address assignments and changes, and automatically responds by redirecting connection requests. This feedback loop eliminates the need for manual intervention while maintaining automated DHCP functionality.
Solution Approach 2:
The information process device acts as an intermediary between the DHCP server and electric appliances. It receives connection requests intended for appliances, redirects them to the correct current IP addresses, and forwards responses back. This intermediary function transparently handles IP address changes without requiring user awareness or action.
2Stability of the object's composition
If users store IP addresses in electric appliances for reuse, then connection consistency is maintained, but manual redirection from stored IP addresses to assigned IP addresses is still required when IP addresses change
Solution Approach 1:
The information process device preliminarily detects and records the association between electric appliance identifiers and their IP addresses before any changes occur. When an appliance reconnects or receives a new IP address, the device has already prepared the redirection mapping, enabling immediate automatic redirection without requiring users to manually update stored IP addresses.
3Ease of operation
If the system monitors and redirects IP address changes automatically, then user-friendliness improves, but the complexity of the information process device increases
Solution Approach 1:
The information process device performs multiple functions within a single system: it detects electric appliance connections, acquires IP address information, stores association data, monitors for reconnections, and redirects connection requests. By consolidating these functions into one multi-functional device rather than separate systems, the overall network complexity is reduced while maintaining automated IP address management.

AI summary
In order to attain the above object, an information process device of the present invention detects a connection of an electric appliance 100 to a network, transmits an IP address of the electric appliance 100, acquires the IP address of the detected electric appliance 100, acquires association information associating the IP address with an identifier identifying the electric appliance 100, re-acquires the IP address of the re-detected electric appliance based on the acquired association information, and redirects a connection request from an IP address associated with the identifier to the re-acquired IP address based on the acquired association information.
