IP addressing Chap 8 Flashcards
process of sending a packet from one host to an individual host
unicast
process of sending a packet from one host to all hosts in the network
broadcast
process of sending a packet from one host to a selected group of hosts, possibly in different networks
multicast
IPv4 range of multicast addresses
224.0.0.0 to 239.255.255.255
IPv4 multicast address range reserved for link local addresses
224.0.0.0 to 224.0.0.255
IPv4 range of addresses class A private addresses
10.0.0.0 to 10.255.255.255 (10.0.0.0/8)
IPv4 range of addresses class B private addresses
172.16.0.0 to 172.31.255.255 (172.16.0.0/12)
IPv4 range of addresses class C private addresses
192.168.0.0 to 192.168.255.255 (192.168.0.0/16)
IPv4 range of addresses reserved for loopback
127.0.0.0 to 127.255.255.255
IPv4 addresses that are designated for link local usage
169.254.0.0 to 169.254.255.255 (169.254.0.0/16)
Test-net address range
192.0.2.0 to 192.0.2.255 (192.0.2.0/24)
Experimental address range
240.0.0.0 to 255.255.255.254
Class A range
0.0.0.0/8 to 127.0.0.0/8
Class B range
128.0.0.0/16 to 191.255.0.0/16
Class C range
192.0.0.0/24 to 223.255.255.0/24
3 categories of tools used for the migration of ipv4 to ipv6
dual stack
tunneling
translation
128 bit address/340 undecillion addresses
ipv6
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
