32 bit address/4.3 billion addresses

ipv4

transports an ipv6 packet over ipv4 networks

tunneling

allows nat to be used in both ipv6 and ipv4 networds

translation

allows ipv4 and ipv6 to coexist on the same network

dual stack

An IPv6 address is any IPv6 unicast address that can be assigned to multiple devices

anycast

An IPv6 address used to send a single IPv6 packet to multiple destinations.

multicast

An IPv6 address that uniquely identifies an interface on an IPv6-enabled device

unicast

How does IPv6 represent the prefix portion of the address equivalent to subnet mask in ipv4?

with prefix length

IPv6 address that is similar to a public ipv4 address

global unicast

ipv6 address used to communicate with other devices on the same local link.

link-local

IPv6 address used by a host to send a packet to itself and it cannot be assigned to a physical interface

loopback

address used as a source address when the device does not yet have a permanent IPv6 address or when the source of the packet is irrelevant to the destination. an all-0s address represented in the compressed format as ::/128 or just :: in the compressed format.

unspecified address

addresses used for local addressing within a site or between a limited number of sites. These addresses should not be routable in the global IPv6. the range of FC00::/7 to FDFF::/7.

unique local

addresses used to help transition from IPv4 to IPv6.

ipv4 embedded

What range are ipv6 link local addresses in?

FE80::/10

Which address is usually used as the default gateway in ipv6

link local

unique, internet-routable ipv6 address

global unicast

ipv6 address represented as ::1

loopback

ipv6 address represented as :: in compressed format-cannot be assigned to an interface

unspecified

typical ipv6 prefix used to indicate the network portion of the address

/64

used to communicate with other devices on the same ipv6 subnet

link-local

3 parts of the ipv6 global unicast address

global routing prefix subnet id interface id

portion of the ipv6 address. prefix, or network, portion of the address that is assigned by the provider, such as an ISP, to a customer or site.

global routing prefix

portion of the ipv6 address that is used by an organization to identify subnets within its site

subnet id

portion of the ipv6 address that is equivalent to the host portion of an ipv4 address

interface id

all nodes multicast group

ff02::1

all routers multicast group

ff02::2
