🌐 Level 10: Network — IPv6 Full Stack

IPv6 routing, ::1 localhost, and network health. Everything runs on the local loopback.

Checking...
Step 1
Check IPv6 routes
ip -6 route show
Step 2
Check IPv6 addresses
ip -6 addr show
Step 3
Ping localhost IPv6
ping6 -c 2 ::1
Step 4
Verify hub via IPv6
curl -s http://[::1]:3000/quest-status | python3 -m json.tool
💡 Why this matters:
The NPR stack uses IPv6 loopback (::1) exclusively. This is more secure (not exposed on LAN) and future-proof. If ::1 routing isn't working, the hub can't serve pages. Most modern Linux distros have this by default.
