Which sublayer enables IPv4 and IPv6 to utilize the same network interface and media?

Explanation:
Multiplexing IPv4 and IPv6 on the same link is handled by the Logical Link Control sublayer. This LLC layer sits in the data-link layer above the MAC and provides a common interface to the network layer, using header fields to indicate which upper-layer protocol the frame carries. Because of this, both IPv4 and IPv6 frames can share the same network interface and media without conflict. The MAC sublayer handles addressing and access to the medium, not protocol multiplexing, and the physical layer is just the actual transmission media. The transport layer operates above IP, so it isn’t involved in how the data link carries multiple IP versions.
