The Internet: Addressing The Internet Flashcards
IP stands for
internet protocol
IP address
a unique numerical label assigned to each device connected to a computer network or the internet, allowing for communication and data transmission between devices
how many types of IP addresses are there and what are they
two: IPv4 and IPv6
IPv4 formt
Each IP address is split into 4 numbers, and each of those numbers can range from 0-255
(0-255).(0-255).(0-255).(0.255)
how do computing devices store IPv4 addresses
in binary
in addition to the actual message sent, what needs to be sent when computers communicate with each other
the IP address of the receiving device and its own IP address so it an revieve stuff back
why was the IPv6 created
bc we were running out of IPv4 addresses
hexadecimal system
for humans to convert numbers easier -> goes by a base 16 system
what does it mean that hexsadecimal system had a base 16 system
so yk how we have 10s 100s 1000s for the normal ; for hexadecimal it would be 16s, 256s, 4096
what numbers can hexadecimal numbers consist of
0123456789ABCDEF
A
10
B
11
C
12
D
13
E
14
F

formula to find the largest number that can be represented by a number of digits
16^n - 1 where n is the number of digits

A website decides to use 10-digit hexadecimal numbers as unique identifiers for their users. Here are a few examples:
1FEBCD128B
79ACAA349F
674ABF9872
What’s the maximum number of users that can be represented with these identifiers?
16^0 bc each of the identifiers has 10 digits so each digit has 16 options to choose from so 16^10
dynamic IP address
when ur IP address has the ability to change whenever it pops up on the network
static IP address
IP addresses like Google that are rly fast so they can send and retrieve messages fast
ipv6 IP address format
however many little group thingies you want but there has to be only 4 and each of them are hexadecimal choicesi
what type of IP address is this
ipv4
ipv6
not real
e0f8:af58:eee6:52b
not real bc 52b is only 3 digits

ipv4
IP address protocol
the use of IP addresses to identify Internet-connected devices
IP address hierarchy
a system that organizes addresses for efficient routing by dividing them into network and host portions, enabling routers to quickly identify the destination network and then the specific device within that network.
example of IP address hierarchy
phone numbers:
look at study stuff for example explanation
subnetworks
the octets that IP addresses are broken into that each address a more specific thing to be directed to
each of the groups in an ipv4 Ip address are called
octets
If the UMich network instead used
[3] bits to identify a department network, how many departments could they differentiate between?
8 bc you have to do 2^3 bc diff possibilities
Ip address
A number that identifies Internet-connected devices
