Frequently Asked Questions
What is a subnet?
A subnet divides a large network into smaller, more efficient networks. Each subnet has its own range of IP addresses.
What is CIDR notation?
CIDR (Classless Inter-Domain Routing) notation, e.g., /24, specifies the number of network bits in an IP address.
How many hosts in a /24 subnet?
A /24 subnet has 254 usable host addresses (256 total minus network and broadcast addresses).
