I’m pretty certain it’s 64 bits for the interface identifier, but I should double-check my notes just to be safe.

I’m a bit confused; I thought it might be 128 bits total, but I think the interface part is 64 bits.

I remember practicing a question like this, and I believe it was also about the 64 bits for the interface identifier.

I think the interface identifier for IPv6 unicast addresses is 64 bits, but I’m not 100% sure.
