Preguntas Frecuentes
What is a subnet mask?
A subnet mask is a 32-bit number that divides an IP address into network and host portions, enabling proper routing and network segmentation.
What does CIDR notation mean?
CIDR (Classless Inter-Domain Routing) notation uses a forward slash followed by the number of network bits (e.g., /24), which is more efficient than traditional subnet masks.
How many hosts can I have in a /24 network?
A /24 network has 254 usable host addresses (256 total minus network and broadcast addresses).
Can I calculate IPv6 subnets with this tool?
This calculator focuses on IPv4. For IPv6, you would need a dedicated IPv6 calculator as the subnet structure differs significantly.
