How do I find my IPv6 link-local address?
After a global IPv6 unicast address is configured on the interface, an IPv6 link-local address is automatically generated. After the ipv6 address auto link-local command is run on the interface, an IPv6 link-local address is automatically generated.
What is the range for an IPv6 link-local address?
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).
What do IPv6 link local addresses start with?
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.
What type of IPv6 address is this?
A single interface can be assigned multiple IPv6 addresses of any type. The three types of IPv6 addresses are: unicast, anycast, and multicast….IPv6 Addressing.
|Allocation||Prefix (binary)||Fraction of Address Space|
|Reserved for NSAP Allocation||0000 001||1/128|
|Reserved for IPX Allocation||0000 010||1/128|
What are the different types of IPv6 addresses?
The three types of IPv6 addresses are: unicast, anycast, and multicast.
- Unicast addresses identify a single interface.
- Anycast addresses identify a set of interfaces in such a way that a packet sent to an anycast address is delivered to a member of the set.
Can I ping IPv6 link-local address?
To ping using IPv6 between two link-local hosts Use ipv6 if on Host B to obtain the link-local address for the Ethernet interface. Example: The link-local address of Host B is fe80::260:97ff:fe02:6ea5. From Host A, ping Host B using Ping6.exe.
How is an IPv6 address written and displayed?
IPv6 uses 128-bit (2128) addresses, allowing 3.4 x 1038 unique IP addresses. This is equal to 340 trillion trillion trillion IP addresses. IPv6 is written in hexadecimal notation, separated into 8 groups of 16 bits by the colons, thus (8 x 16 = 128) bits in total.
What does FF00 ::/ 8 mean?
IPv6 multicast addresses use the prefix ff00::/8, shown in Table 4-10, which is equivalent to the IPv4 multicast address 224.0. 0.0/4. A packet sent to a multicast group always has a unicast source address. A multicast address can never be the source address. Unlike IPv4, there is no broadcast address in IPv6.
