IPv6 Flashcards
What is the “address” and mask of an Unspecified IPv6 address?
::/128
What is the address and mask of the Local Loopback IPv6 address?
::1/128
What is the address range and mask for a Global Unicast IPv6 address?
2000::/3
The range would be any address starting with 2000 through 3FFF
What is the address range and mask for a multicast IPv6 address?
FF00::/8
What is the address range and mask for a Link-Local IPv6 address?
FE80::/10
What is the address range and mask for an IPv6 Unique Local Address (aka private addresses)?
FC00::/7
How is an IPv4 address embedded into an IPv6 address?
The first 96 bits (6 segments) of the IPv6 address are all zeros while the IPv4 address is then converted to Hexadecimal and added to the end.
Define DAD
Duplicate Address Detection - When an ethernet interface is trying to determine if any other devices are using the link-local address that the device is trying to generate.
Define NS
Neighbor Solicitation - a message is sent by a node to determine the link-layer address of a neighbor, or to verify that a neighbor is still reachable via a cached link-layer address. NS are also used for Duplicate Address Detection.
Define NA
Neighbor Advertisement - a message is sent in response to an NS message. A node may also send unsolicited NAs to announce a link-layer address change.
Define RS
Router Solicitation - When an interface becomes enabled, hosts may send out RSes that request that routers generate Router Advertisements (RAs) immediately rather than at their next scheduled time.
Define RA
Router Advertisements - Routers advertise their presence together with various link and Internet parameters either periodically, or in response to an RS message. RAs contain prefixes that are used for determining whether another address shares the same link (on-link determination) and/or address configuration, a suggested hop limit value, and so forth.
What are the RFCs for IPv6?
RCF 2460, RFC 8200
RFC 8200 supersedes RFC 2460
