In this Modern Age, we all know IP addresses are like the unique identifier for every device that is connected to a network. The IP addresses are the reason devices are able to communicate with eachother.
So what is the format of IP addresses?
The identity and IPs were first made in the format of IPv4 - which is made with binary numbers of four number, each number containing 8 bits
IPv4: 192.168.1.1
_ _ _ _ _ _ _ _ . _ _ _ _ _ _ _ _ . _ _ _ _ _ _ _ _ . _ _ _ _ _ _ _ _
IPv6 :2001:0db8:85a3:0000:0000:8a2e:0370:7334
each number also represents a different sense of belonging of the IP address in the networK , In IPv4 only certain number of IP addresses can be created so IPv6 were introducted it is of the format with hexadecimal numbers and colon and can make vast number of IPs
Did You Know?
You can find your device's IP address using the 'ipconfig' comment in the terminal
What is a subnet?
Subnet is a smaller portion of network that is used for easier organization of network and navigation
Every IP Address Has A
Host Part - used by the router to send data to exact network
Network Part - used to send data to the exact device
The network part is responsible for identify the network group a IP belongs to, all devices in a same network share this part wheras the
The Host part specfies the device in a network and is unique within a network
What is the subnet mask ?
The subnet mask is used to define the number of bits of IP that is used to define the network part of a IP
it is carried out with a help of CIDR - Classless Inter Domain Routing
IP_address / number_of_bits
example: 192.168.1.0/24
let's breakdown this example and understand
in this IP address it means from the total of 32 bits - 24 bits are used by the network part and remaining 8 are used by the host part
network part -> 24
host part -> 8
the number IP 2^8 = 256
