Non-IPv4 addresses fall back to exact-style binding when a prefix mode is selected.
How it works
Mobile networks and CGNAT change IPs often. Exact matching causes “link not valid from this IP” failures after minting on Wi‑Fi and downloading on cellular.
Common problems
Phone downloads fail after minting on Wi‑Fi
IP changed. Use first2 / first3 or all.
Hotlink abuse after All IPs
Tighten binding and keep short Symlink expiry + Symlink max uses.
