In this chapter, you learned about IPv4 and IPv6 addressing. The following topics were explored:
■ Private and public IP addresses, and when to use each
■ Determining the network size, including the number and type of locations and the number and type of devices at each location
■ Hierarchical addressing, route summarization, and the role of classful and classless routing protocols and fixed-length and variable-length subnet masks
■ Static and dynamic (DHCP) address assignment
■ Static and dynamic (DNS) name resolution
■ Features of IPv6, including its 128-bit addresses
■ Types of IPv6 addresses: unicast (one-to-one), anycast (one-to-nearest), and multicast (one-to-many)
■ Types of IPv6 unicast addresses: global aggregatable, link-local, and IPv4-compatible
■ Types of IPv6 address assignment: static or dynamic, which includes using link-local addresses, stateless autoconfiguration, and stateful using DHCPv6
■ Types of IPv6 name resolution: static or dynamic using DNS servers that have IPv6 protocol stack support
■ IPv4-to-IPv6 transition strategies, including dual-stack use, tunneling mechanisms, and translation mechanisms
■ IPv6 routing protocols, including RIPng, EIGRP for IPv6, OSPFv3, IS-ISv6, and BGP4+
