Question 1

What is the total length of an IPv6 address?

Accepted Answer

128 bits

Answer

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

Question 2

Which IPv6 address type (FC00::/7) is analogous to IPv4 private address ranges such as RFC 1918?

Accepted Answer

Unique local addresses (FC00::/7)

Answer

Unique local addresses (FC00::/7, commonly FD00::/8) are the IPv6 equivalent of IPv4 private addresses and are not routable on the public internet.

Question 3

What is the primary purpose of IPv6 link-local addresses (FE80::/10)?

Accepted Answer

To enable communication between nodes on the same link without requiring a router

Answer

Link-local addresses are used for communication between devices on the same network segment and are automatically configured on every IPv6-enabled interface.

Question 4

Which protocol replaces ARP in IPv6 networks for resolving IPv6 addresses to MAC addresses?

Accepted Answer

ICMPv6 Neighbor Discovery Protocol (NDP)

Answer

IPv6 uses ICMPv6 Neighbor Discovery Protocol (NDP) instead of ARP, using multicast Neighbor Solicitation and Neighbor Advertisement messages for address resolution.

Question 5

What does SLAAC (Stateless Address Autoconfiguration) allow an IPv6 host to do?

Accepted Answer

Automatically configure its own IPv6 address using Router Advertisements without a DHCP server

Answer

SLAAC allows IPv6 hosts to automatically derive their own addresses from the prefix advertised in Router Advertisements, requiring no DHCPv6 server.
