About Free Online IPv4 Subnet Calculator - Calculate Network Data in Seconds
The IPv4 IPv6 subnet calculator is essential for network administrators, IT professionals, and anyone working with IP addresses. It provides a free, easy-to-use solution for calculating crucial network data, such as broadcast addresses, network addresses, Cisco wildcard masks, host ranges, and host quantities. By simply entering an IP address and netmask value (in either decimal or CIDR form), our subnet calculator will do the calculations for you quickly and accurately.
• Broadcast Address Calculation: Determine the broadcast address for the specified IP address and netmask.
• Network Address Calculation: Identify the network address for your IP address and netmask input.
• Cisco Wildcard Mask: Calculate the inverse netmask used for Access Control Lists (ACLs) in Cisco routers.
• Host Range: Generate valid host IP addresses based on your input data.
• Host Quantity: Calculate the possible hosts for the given IP address and netmask.
IP addresses are divided into five classes (A through E), with each type having a different range of valid IP addresses. Knowing the class of IP addresses, you're working with is essential for accurate calculations using the IPv4 subnet calculator and IPv6 subnet calculator.
• Class A: Ranges from 1.0.0.1 to 126.255.255.254, with 16 million hosts on each of the 127 networks.
• Class B: Ranges from 128.1.0.1 to 191.255.255.254, with 65,000 hosts on each of the 16,000 networks.
• Class C: Ranges from 192.0.1.1 to 223.255.254.254, with 254 hosts on the 2 million networks.
• Class D: Addresses in the 224.0.0.0 to 239.255.255.255 range are reserved for multicast use.
• Class E: Addresses in the 240.0.0.0 to 255.255.255.255 range are reserved for experimental purposes and are not commonly used.
Our IPv4 subnet calculator and IPv6 subnet Calculator offer a convenient, one-stop solution for calculating critical network parameters. This powerful, user-friendly tool saves time and avoids errors in network planning, management, and troubleshooting.
