Frequently Asked Questions
What is a subnet mask?
A subnet mask separates the network portion from the host portion of an IP address. For example, /24 (255.255.255.0) means the first 24 bits identify the network and the last 8 bits identify hosts.
What is CIDR notation?
CIDR notation (e.g., /24) indicates the number of network bits in the subnet mask. /24 is equivalent to the dotted-decimal mask 255.255.255.0.
How is the number of usable hosts calculated?
Total addresses = 2^(32 - prefix length). Usable hosts = total addresses minus 2 (one for the network address and one for the broadcast address).
