|
How many bits make up an IPV6 address?
|
128 bits
|
|
What 2 features are built into IPV6?
|
Mobile IP & IPSEC
|
|
What are the 8 header fields in IPV6?
|
Version, traffic class, flow label, payload length, hop limit, next header, source address, destination address
|
|
What is zero compression and what is a major restriction when using this?
|
Consecutive fields of zeroes in an IPV6 address can be expressed with two colons. Zero compression can only be used once in a single address.
|
|
What is leading zero compression?
|
Leading zeros in any 16-bit field can be dropped, but each block where the leading zeros were dropped must have at least one remaining number, even if it is zero.
|
|
What is the format of an IPV6 address?
|
8 sets of 16 bits (4 hex digits) separated by colons. 1234:0000:5678:0000:9ABC:0000:DEFF:0000
|
|
Name the IPV6 address types.
|
1. aggregateable global unicast address, 2. Site-Local address, 3. Link-Local address, 4. multicast address, 5. anycast address
|
|
Describe aggregateable global unicast addresses.
|
Equivalent to the IPV4 public address. They are fully routable and are used for Internet access. Aggregateable refers to the ability to summarize these addresses to make routing more efficient.
|
|
Describe Site-Local addresses.
|
Equivalent to the IPV4 private address classes. Hosts using these address can communicate with each other thoughout the site, but are not able to reach Internet or remote hosts.
|
|
Describe Link-Local addresses.
|
Smaller in scope than Site-Local. These addresses are local to a physical link. Link-Local is not used at all in forwarding data.
|
|
What is IPV6's equivalent to ARP?
|
Neighbor Discovery Protocol (NDP)
|
|
What are the identification traits of the following address types: global, multicast, Site-Local, Link-Local, & IPV4 equivalent?
|
These addresses are identified by their initial bits. 001 - Global, FF - Multicast, FEC - Site-Local, FE8 - Link-Local, ::x.x.x.x or 0:0:0:0:0:0:x.x.x.x - IPv4 equivalent (1st 96 bits are zero)
|
|
What is the IPV6 loopback address?
|
0:0:0:0:0:0:0:1 or ::1
|
|
What is the IPV6 unspecified address?
|
It is all zeros or ::/128 and is used to represent an unkown address.
|
|
What is the IPV6 equivalent to a subnet?
|
Site-Level Aggregator (SLA)
|
