IP Saving with Dropdown Selection in Relay

[vbramhadevi]

Description

Improve the Relay startup process by allowing users to enter IP addresses and automatically save them for future use.

The system should store entered IP addresses in a persistent saved list and display them in a dropdown menu. This allows users to quickly select previously used IPs without manually retyping them every time.

The feature must include IP validation, prevent duplicate entries, and ensure saved IPs persist across application restarts.

Tasks

• Add IP address validation logic
• Implement persistent storage for saved IP addresses (config file or local storage)
• Create dropdown UI component to display saved IPs
• Prevent duplicate IP entries
• Connect dropdown selection to Relay startup logic
• Test persistence after application restart

Acceptance Criteria

• User can enter a new IP and start Relay successfully
• Entered IP is automatically saved to a persistent list
• Dropdown displays previously saved IP addresses
• Selecting an IP from dropdown auto-fills and starts Relay
• Duplicate IPs are not stored
• Invalid IP format shows validation error
• Saved IPs persist after restarting the application
