By default, IPv6 configures link-local IP addresses for each interface corresponding to installed Ethernet network adapters. Link-local addresses have the prefix fe80::/64. The last 64 bits of the IPv6 address is known as the interface identifier and is derived from the 48-bit MAC address of the network adapter.

DNS issues on the network while IPv6 enabled on clients Jul 26, 2019 RFC 4193 - Unique Local IPv6 Unicast Addresses IPv6 local addresses would have to be flat-routed even over the wide area Internet. Thus, packets whose destination address is an IPv6 local address could be routed over the wide area only if the corresponding /48 prefix were carried by the wide area routing protocol in use, such as BGP.

Figure 4-6 shows another type of IPv6 unicast address, the unique local address (ULA), which is the counterpart of IPv4 private addresses. Unique local addresses are also known as private IPv6 addresses or local IPv6 addresses (not to be confused with link-local addresses). Subnet masks (IPv4) and prefixes (IPv6) - IBM Subnet masks (IPv4) and prefixes (IPv6) identify the range of IP addresses that make up a subnet, or group of IP addresses on the same network. For example, a subnet can be used to identify all the machines in a building, department, geographic location, or on the same local area network (LAN). IPv6 DNS: Understanding IPv6 and a Quick Implementation Guide While IPv6 is a big step forward, DNS systems leveraging IPv6 have the same capabilities. As you move to the next generation of IP, consider in tandem using the next generation of DNS technology. Modern DNS providers like NS1 operate IPv6 DNS servers with vastly improved performance, light-speed propagation and advanced traffic management features.
