Study Notes

IP address is a unique identifier assigned to a device for communication on a network.
IP addresses cannot be the same in two devices in a network to prevent conflict errors.
Two versions of IP addresses exist: IPV4 (32 bits) and IPV6 (128 bits).
IP addresses consist of network and host parts, identified by looking at the first digit.
Class A: Network ID is the first number, Subnet mask is 255.0.0.0, and Broadcast ID is 255.255.255.255.
Class B: Network ID is the first two numbers, Subnet mask is 255.255.0.0, and Broadcast ID is 255.255.255.255.
Class C: Network ID is the first three numbers, Subnet mask is 255.255.255.0, and Broadcast ID is 255.255.255.255.
Local Area Network creation requires a public IP address, with the network ID kept constant and host ID changed for new devices.
IP addresses have various uses:
- IP address blocking for website/service access prevention.
- IP address tracking for online activity monitoring.
- Identifying devices on a network for communication and resource access.
- Routing traffic on the internet to find server addresses.
- Security purposes like unauthorized access blocking.
- Geolocation to determine approximate device locations.
- Troubleshooting network problems by identifying IP address locations.
