What is the difference between IPv4 and IPv6?

IPv4 uses 32-bit addresses (e.g., 192.168.1.1), allowing about 4.3 billion addresses. IPv6 uses 128-bit addresses (e.g., 2001:db8::1), allowing virtually unlimited addresses.

What is a private IP address?

Private IP addresses are used within local networks and are not routable on the internet. IPv4 private ranges: 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16.

What is CIDR notation?

CIDR (Classless Inter-Domain Routing) notation specifies an IP address and its routing prefix, e.g., 192.168.1.0/24 means the first 24 bits are the network prefix.
