MACs are computed directly from cryptographic hashes. For normal ZeroTier P2P traffic the MAC and Ethernet header are elided entirely too, which saves about 14 bytes of per-frame overhead.

Wait, are we talking about MAC as in cryptographic Message Authentication Code, or MAC as in ethernet Medium Access Control (addresses)?

MAC as in 48-bit Ethernet addresses.

There's a tiny chance of a collision, but for it to be meaningful you'd have to have a virtual LAN with millions of devices on it.
