CCNA 1.15: Compare and contrast IPv6 address types (Global unicast, Unique local, Link local, Multicast, Modified EUI 64, Autoconfiguration, Anycast)

Overview: IPv6 address types consist of unicast and multicast addresses along with anycast addresses. With IPv6, an interface is expected to have multiple addresses. It also listens to various multicast addresses. IPv4 addresses are either unicast, multicast or broadcast.  In IPv6, broadcast addresses no longer exist.   Study notes: Unicast – uniquely identifies an interface. […]


CCNA 1.14: Configure and verify IPv6 Stateless Address Auto Configuration

Overview: IPv6 Stateless address autoconfiguration is similar to DHCP in IPv4.  Routers running IPv6 can give the network prefix and gateway address to clients looking for an IPv6 address.  The device needs a global IPv6 address to be able to connect to the network (and internet).  IPv6 stateless autoconfiguration is a way for a device […]


CCNA 1.13: Configure, verify and troubleshoot IPv6 addressing

Overview: IPv6 addressing was designed to address the deficiencies in IPv4.  It is based on 128-bit hexadecimal IP addresses, which provide a much greater amount of addresses (3.4×10^38 or 340 undecillion) while still meeting requirements to be heirarchical and scalable.  So what happened to IPv5? I always assumed IPv4 was so because it used four […]


CCNA-1.12: Identify the appropriate IPv6 addressing scheme to satisfy addressing requirements in a LAN/WAN environment

Overview: IPv6 addressing is designed differently than IPv4.  Subnetting is used in IPv4 to more efficiently use the small number of available addresses. IPv6 has a large enough address space without subnetting to accommodate devices for the foreseeable future.  The local area subnet always uses 64 bits for the routing prefix and 64 bits for […]
