IP Addresses Flashcards
what does IP stand for
internet protocol
what are the two types of IP addresses
IPv4
IPv6
what are IP addresses
logical addresses defining the connection of a device to the internet
how long are IPv4 addresses
32 bits
(4 bytes)
can two devices on the internet have the same IP address at the same time
no
what are the two notations for IP addresses
binary
dotted
example of dotted notation IP address
172.20.16.233
what numbers do the ip addresses range from
0 -255
0.0.0.0 to 255.255.255.255
are numbers allowed to be prefixed with 0 in IPv4 addressing eg 10.056.57.2
no
why was IPv6 invented
worried that we would run out of IPv4 addresses
what is multicast addressing
instead of sending a packet to one IP address, it is sent to a number of nodes
(one to many communication)
what is anycast addressing
network decides which one of the nodes to deliver to
could be random or based on nearest
main difference between IPv6 and IPv4
IPv6 has no fragmentation as every network using IPv6 must be able to transfer a minimum of 1280
IPv6 has longer addresses
what is unicast
sending message from one host to an individual host
what is multicast
sending message from 1 host to a selected group
