what i have been understand throught this session
When you open a website, your computer communicates with another computer on the internet.
This communication happens using IP addresses and subnets.
what i have been learned:
- What is an IP Address
- Types of IP Address
- What is Subnet
- Why Subnet is used *Real-world example
as per mythought process What is an IP Address?
An IP address is a unique identifier assigned to each device on a network.the ip address will be divide into parts 8bits-8bits-8bits-8bits which is totally 32bits.actually every ip is will be in two different types of port which is network port and host port the first 24bits will be network port and last remaining is the host port the cidr will works thought the process of workflow
you can ask what is cidr calculator ??
which is used to set the count,first usable ip,netmask,cidr base ip,broadcast ip by using this which is used to be calculated
Example IP addresses
Just like our home address helps people find your house,
an IP address helps computers find each other on the internet.
- 192.168.1.1
- 8.8.8.8
- 172.16.0.1
There are some Types of IP Address
1. Public IP Address
Used on the internet and assigned by ISP(internet acces protocol)
Example:
8.8.8.8
2. Private IP Address
Used inside local networks (WiFi, office, home).
Example ranges:
- 192.168.x.x
- 10.x.x.x
- 172.16.x.x
What is Subnet?
A Subnet means dividing a large network into smaller networks.
Subnet = Sub Network
Subnet helps:
- Reduce network traffic
- Improve performance
- Increase security
- Better network
Example Without Subnet
All devices in one network:
192.168.1.1
192.168.1.2
192.168.1.3
192.168.1.254
This creates heavy traffic.
some Example With Subnet
Subnet 1
192.168.1.1 – 192.168.1.50
Subnet 2
192.168.1.51 – 192.168.1.100
Subnet 3
192.168.1.101 – 192.168.1.150
Now network is faster and organized.
What is Subnet Mask?
Subnet mask defines network and host portion.
Example:
IP Address: 192.168.1.10
Subnet Mask: 255.255.255.0
Network part → 192.168.1
Host part → 10
how in Real World works
Network → Building
Subnet → Floor
IP Address → Room number
Example:
Building A
Floor 1 → Subnet
Room 101 → IP Address
Conclusion
- IP Address identifies devices
- Subnet divides networks
- Subnet improves performance and security
- Subnet mask defines network range
