Examining IPv6 Addresses Flashcards
What is an IPv6 address?
Utilizes 128-bit addresses, enabling an extensive number of unique IP addresses.
What portion of the IPv6 address is reserved for the network prefix?
Portions of the address are reserved for the network prefix (like an IPv4 network ID).
What portion of the IPv6 address is reserved for the interface identifier?
The remaining portion is reserved for the interface identifier (like an IPv4 host ID).
What are some benefits of IPv6?
Vast Address Pool, Simplified Routing and Header Format, Elimination of Broadcast Communications, Stateless and Stateful Configuration, Inherent Security Features, Enhanced Support for Mobile Nodes.
What does the vast address pool of IPv6 remove the need for?
Removes the need for NAT, simplifying network design.
What is the header format of IPv6?
Simplified packet header.
What does IPv6 replace broadcasting with?
Replaces broadcasting with multicast and anycast.
What does SLAAC stand for?
StateLess Address AutoConfiguration.
What does SLAAC enable devices to do?
Automatically configure their own IPv6 addresses without the need for a server-based addressing mechanism like DHCP.
What are the different types of IPv6 addresses?
Global Unicast Addresses, Unique Local Addresses, Link-Local Addresses, Multicast Addresses, Anycast Addresses, Special Addresses.
What is the prefix for Global Unicast Addresses?
2000::/3.
What is the prefix for Unique Local Addresses?
FC00::/7.
What is the prefix for Link-Local Addresses?
FE80::/10.
What is the prefix for Multicast Addresses?
FF00::/8.
What is an Anycast Address?
Assigned to multiple interfaces, with the nearest one responding.
What is EUI-64?
Converts a 48-bit MAC address to a 64-bit interface identifier for IPv6.
What is the format of EUI-64?
Involves inserting ‘FFFE’ in the middle of the MAC address and inverting the 7th bit (Universal/Local bit).
What are some special addresses in IPv6?
Teredo (Prefix- 2001:/32), 6to4 (Prefix- 2002::/16), ISATAP.
True or False: IPv6 has inherent security features designed with IPsec.
True.
What does Mobile IPv6 enhance?
Reduces latency for mobile connectivity.
