  1. What is the total length of an IPv6 address?

    Answer: 128 bits

    IPv6 addresses are 128 bits long, written as eight groups of four hexadecimal digits separated by colons.

  2. Which IPv6 address prefix is used for link-local addresses?

    Answer: FE80::/10

    IPv6 link-local addresses always start with FE80::/10 and are automatically assigned to every IPv6-enabled interface for local segment communication.

  3. What IPv6 protocol replaces ARP for address resolution?

    Answer: Neighbor Discovery Protocol (NDP)

    NDP uses ICMPv6 Neighbor Solicitation and Neighbor Advertisement messages to resolve IPv6 addresses to MAC addresses, replacing ARP.

  4. Which ICMPv6 message type is sent by a host to discover routers on the local link?

    Answer: Router Solicitation (Type 133)

    A Router Solicitation (ICMPv6 Type 133) is sent by a host to the all-routers multicast address FF02::2 to discover available routers immediately.

  5. What is the IPv6 loopback address?

    Answer: ::1/128

    The IPv6 loopback address is ::1/128, which is the compressed notation for 0000:0000:0000:0000:0000:0000:0000:0001.

  6. Which EUI-64 process is used to auto-generate an IPv6 interface identifier from a MAC address?

    Answer: Insert FF:FE in the middle of the MAC address and flip the 7th bit

    EUI-64 splits the 48-bit MAC address in half, inserts FF:FE in the middle to create 64 bits, and flips the Universal/Local (U/L) bit.
