Choose a match for every item. Use each answer once.

CIDR expresses network size through prefix length rather than legacy address classes.

IPv6 greatly expands address space and uses a different base packet-header design from IPv4.

IPv4's address format provides a finite space of roughly four billion possible addresses.

A subnet mask determines which address bits belong to the local network portion.
