Types of nodes
- IPv4-only node (does not understand IPv6)
- IPv6/IPv4 node (understands both IPv4 and IPv6l)
- IPv6-only node (does not understand IPv4)
- IPv6/IPv4 and IPv4-only are both IPv4 nodes
- IPv6/IPv4 and IPv6-only are both IPv6 nodes
IPv4-Mapped IPv6 address
- used to represent IPv4 addresses in an IPv6 address format
- architected prefix ::ffff:0:0/96
- ::ffff:n.n.n.n, where n.n.n.n is an IPv4 address
