I'd like to suggest adding a fourth option called "Dynamic Client Subnet" to the EDNS Client Subnet override settings. This option would automatically use the client device's current IP subnet rather than predetermined DNS subnets (Auto) or manually configured subnets (Custom).

Current limitations:

"No ECS" disables the feature entirely

"Auto" only uses DNS subnets which may not reflect actual client location

"Custom" requires manual configuration and doesn't adapt when devices change networks or locations

Benefits of Dynamic Client Subnet:

Automatically adapts as devices move between networks

Provides more accurate location-based DNS resolution

Eliminates the need for manual subnet updates

Improves content delivery and reduces latency by ensuring accurate geolocation

This enhancement would be particularly valuable for mobile devices that frequently connect to different networks.
