The IPv6 Link Local addresses are made from the first 64-bit reservation (FE80::/64) and remaining bits are taken from the MAC address of the interface. But, MAC addresses are 48 bit numbers. 64+48 is only 112bits to form IPv6 address (IPv6 addresses are 128 bit in length).

Does IPv6 have private addresses?

In IPv6 we don’t have an exclusive choice between assigning a network interface an internal private address or an external public Internet address – known as an IPv6 Global Unicast Addresses (GUA) (RFC 4291).

Do you need to subnet IPv6?

6: You don’t need a traditional subnet mask IPv6 also uses subnets, but the subnet ID is built into the address. In an IPv6 address, the first 48 bits are the network prefix. The next 16 bits are the subnet ID and are used for defining subnets.

What are two types of IPv6 Unicast addresses?

IPv6 Address Types The two currently defined types of unicast addresses are global aggregatable (which is also called global unicast) and link-local. As in IPv4, a subnet prefix in IPv6 is associated with one link.

Why does my WiFi have 3 IPv6 addresses?

Having 3 IP addresses means that your system can be communicated with using three different IP addresses, and most likely means you have WiFi turned on and an Ethernet cable plugged in. One will be the loop back address (127.0. 0.1) and that is only useful on the system itself.

The maximum is 127. The prefix of an IPv6 link-local address is represented textually as “fe80::/n”, where n MAY be any value between 10 and 127. Regardless of the prefix length, the leftmost 10 bits of an IPv6 link-local address MUST be set to binary 1111111010 (hexadecimal fe80).

The first hextet has a range of 1111 1110 1000 0000 (FE80) to 1111 1110 1011 1111 (FEBF). The figure below shows the format of an IPv6 link-local address. IPv6 link-local addresses are also used by IPv6 routing protocols to exchange messages and as the next-hop address in the IPv6 routing table.
