| IPv6 Unique Local address Notation and what is this set used for? |
|
Definition
IPv6 Unique Local Address Notation and Use
fd00::/8 Can be routed within and Intranet but not to the Internet. Can use to create "Hidden Networks". Similar to IPv4 Private Addresses. |

Term
| Global IPv6 Address notation and what are they used for? |
|
Definition
| Global IPv6 addresses start with a 2 or a 3. First 3 bits are always 001. These addresses will route to the Internet. Example: 2020:ab10:5::a234 |

IPv6 Multicast Address Notation and Use
ff00::/8 (first bits= 1111 1111 Used for multicast messages. One host to many hosts at one time. Used with VoIP, Streaming Media, etc. Often used with subscribed users. |

Definition
IPv6 Loopback Address Notation and Use
::1 aka ::1/128 Use is the same as IPv4 loopback address of 127.0.0.1 (self ping testing) |

| IPv6 6to4 Address notation and use |
|
Definition
IPv6 6to4 Address Notation and Use
2002::/16 Use is converting IPv6 to IPv4 when working with mixed hosts. Note this is also a Global IPv6 address. |

|
Term
| Do IPv6 hosts have more than one IPv6 host address? |
|
Definition
Yes, IPv6 hosts typically have multiple addresses.
Link local, Global, etc. |

Term
| IPv6 Teredo address notation and use |
|
Definition
IPv6 Teredo Address Notation and Use
2001::/32(note also a Global IPv6 Address) Used with Teredo for mixed IPv4 / IPv6 hosts for unicast ip traffic. |

Term
What doe the IPv6 Prefix Represent?
(compare to IPv4 address notation) |
|
Definition
The IPv6 Prefix:
Corresponds to IPv4 'Network ID' The rest of the IPv6 address is called the 'Interface ID' which is similar to the IPv4 'host address' |
|
|
Term
| Describe Unicast, Multicast and Anycast messages |
|
Definition
Unicast= one host to one other host
Multicast= One host to many hosts
Anycast= One host to many hosts but one at a time. Packets are relayed. |

Term
How many bits are in an IPv6 address?
How is the address organized?
(how many bits does each character represent?)
(how many bits does each "quad" character set represent?) |
|
Definition
128 bits
Typically noted as 8 sets of 4 hexadecimal characters. Each hex character represents 4 bits. Each "quad" set represents 16 bits. |

Term
| What are the rules for collapsing or simplifying IPv6 addresses?MyFlashcards |
|
Definition
IPv6 Address Collapsing / Simplfying Rules
Leading zeros from any quad set can be eliminated.
Single sets of zeros can be collapsed to :0:.
Multiple sets of zeros can be collapsed to ::. But only one time for the entire address group. |
