IP address and Subnet

IP Address - Internet Protocol Address

Types of IP Addresses
- IPv4
- IPv6

IPv4

• Format: 192.168.1.1
• 32-bit address
• Most commonly used

IPv6

• Format: 2001:0db8:85a3:0000:0000:8a2e:0370:7334

SUBNET - Smaller parts of VPC

Subnetting - process of dividing a large network into smaller network

Why subnet?

• Improves performance
• Enhances security
• Efficient use of IP addresses

SUBNET MASK - Is used to determine which of IP is the host and network part

example ip: 192.10.1.15
192.10.1. = Network part
15 = Host part

CIDR - Classless InterDomain Routing

Example IP:
192.168.1.0/24

• /24 is used to identify which bits First 24 bits are network bits Remaining 8 bits are for hosts
