What is Subnet Calculator?
IP subnet calculation is essential for network design, cloud infrastructure configuration, and firewall rules. A subnet calculator takes an IP address and CIDR notation (like 192.168.1.0/24) and returns the network address, broadcast address, usable host range, subnet mask, wildcard mask, and total host count. DailyDevTools' Subnet Calculator handles both IPv4 and IPv6 subnets.
How to use Subnet Calculator
- 1Enter an IP address with CIDR prefix (e.g., 192.168.1.0/24) or enter IP and subnet mask separately
- 2The calculator instantly shows network address, broadcast address, first and last usable hosts
- 3View the subnet mask in both dotted decimal and CIDR notation
- 4Use the subnet divider to split a network into smaller subnets of a specified size
Frequently asked questions
What does /24 mean in IP notation?
/24 means the first 24 bits of the IP address are the network portion, leaving 8 bits for host addresses. A /24 network has 256 total addresses (2^8), with 254 usable host addresses (subtracting network and broadcast addresses).
What is the difference between a public and private IP range?
Private IP ranges (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) are reserved for internal networks and not routable on the internet. Public IPs are assigned by ISPs and are globally reachable.
What is a CIDR block?
CIDR (Classless Inter-Domain Routing) notation represents an IP address range using an IP address followed by a slash and the prefix length (/24, /16, etc.). A /24 block covers 256 addresses. A /16 covers 65,536.
