Front 25

When can you replace a IPv6 block with ::

Back 25

When there are two consecutive blocks with all zeros you can replace those blocks with ::You can only do this once per IP though

Front 26

When can you remove zeros in an IPv6 address?

Back 26

When a block has leading zeros you can remove them.

Front 27

What do IPv4 addresses have that IPv6 addresses do not?

Back 27

Subnet masks.

Front 28

In IPv6 network se use what to identify the bits of an IPv6 address that are the network address.

Back 28

We still use CIDR notation.

Front 29

Unlike IPv4 there are no _____ addresses in IPv6

Back 29

Broadcast addresses

Front 30

Three address types in IPv6

Back 30

UnicastMulticastAnycast

Front 31

Unicast address

Back 31

one-to-one transmission to / between individual interfaces.

Front 32

Name three types of unicast addresses

Back 32

GlobalLink-LocalUnique Local

Front 33

Format Prefix

Back 33

A sequence of bits that IDs the type of unicast. Each unicast address has an FP.

Front 34

Multicast

Back 34

One-to-many transmissions to groups of interfaces identified by the multicast address

Front 35

Anycast

Back 35

Transmission sent from one device to one-of-many -- whichever device is closest as determined by the number of intermediate routers.

Front 36

Global unicast address

Back 36

The equivalent of a registered (public) IPv4 address. Routable on the Internet

Front 37

FP of a global unicast address

TLA

Back 38

Top Level Aggregator. 13-bit globally unique ID allocated to regional internet registries by the IANA

Front 39
