I understand the format! Vision.io uses the URL structure `https://vision.io/profile/{ethname}.eth` for user profiles. So for the wildcard subdomain routing, when someone visits `bob.eth.vision.io`, it should redirect to `https://vision.io/profile/bob.eth`.

Let me create a system that:
1. Handles wildcard DNS for `*.eth.vision.io`
2. Extracts the ENS name from the subdomain
3. Redirects to the correct Vision.io profile URL format
4. Optionally validates that it's a real ENS name
5. Handles edge cases and errors


Perfect! Now I understand the Vision.io URL structure. Here's a complete implementation for routing {name}.eth.vision.io to https://vision.io/profile/{name}.eth:

Usage Examples:
vitalik.eth.vision.io → https://vision.io/profile/vitalik.eth
abra.eth.vision.io → https://vision.io/profile/abra.eth
bob.eth.vision.io → https://vision.io/profile/bob.eth

This system will handle the wildcard routing and redirect users to the correct Vision.io profile format!
