IPv6 Static Routing is a technique to manually add an entry in the routing table of a router. The main benefits of using IPv6 static routes are better security and efficiency. However, there is one huge disadvantage which is the lack of automatic re-routing around network failures and topology changes.

When a router's interface is configured with an IPv6 global unicast address and the interface is in up/up status, the router automatically adds a Connected route entry and a Local route entry into the routing table.

Prior to Windows Vista and Windows Server 2008, Windows hosts used only MAC addresses to create Interface Identifiers (EUI-64). Globally unique addresses and Link-local ones were created using the segment's prefix plus the EUI-64 identifier which is generated from the physical address of the host. With the rise of network security, this was found to be a security vulnerability because an IPv6 address can be easily tied to a MAC address, which uniquely identifies physical equipment.

Stateless Dynamic Host Configuration Protocol service for IPv6 (Stateless DHCPv6) is used by nodes to obtain other information, such as a DNS server list and a domain name, that does not require the maintenance of any dynamic state for individual nodes. A node that uses stateless DHCP must have obtained its IPv6 addresses through some other mechanism usually SLAAC.

IPv6 Neighbor Discovery Protocol defines a more secure and efficient way of handling the Layer 3 to Layer 2 resolution process using multicast messages instead of broadcast like in IPv4 ARP. IPv6 ND is also used in more advanced services like Router Discovery (RD), Address autoconfiguration (SLAAC), and Duplicate address detection (DAD).

Stateless Address Autoconfiguration (SLAAC) is a mechanism that enables hosts on a network segment to auto-configure a unique global IPv6 address with no device keeping track of which address is assigned to which host.

In this lesson, we are going to examine the differences in how IPv6 operates compared to IPv4. We will compare the IPv6 header to the IPv4 header and talk about the new IPv6 extension headers.

In this lesson, we are going to look at all types of IPv6 addresses in the unicast, multicast, and anycast categories. We will examine the global unicast, both link-local and unique local addresses, embedded IPv4, and some special types like the loopback and the unspecified address.
