CIDR Cheat Sheet. Here is some explanation. Prefix is bit count for network address; Amount Of a Class C is how many C class network can be created in this network; Potential Hosts is the count of IP numbers; Actual Hosts is the count of usable IP numbers because 1 IP is used for network address and 1 IP is used for broadcast purposes.
Addresses / Usable Netmask /30: 4 / 2: 255.255.255.252 /29: 8 / 6: 255.255.255.248 /28: 16 / 14: 255.255.255.240 /27: 32 / 30: 255.255.255.224 /26: 64 / 62: 255.255 IP Subnet Calculator This free online IP subnet calculator covers both IPv4 and IPv6 protocols, providing information such as IP address, network address, subnet mask, IP range, and more. Also, explore hundreds of other math, financial, fitness, and health calculators. IP Calculator / IP Subnetting IP Calculator. ipcalc takes an IP address and netmask and calculates the resulting broadcast, network, Cisco wildcard mask, and host range. By giving a second netmask, you can design subnets and supernets. It is also intended to be a teaching tool and presents the subnetting results as easy-to-understand binary values. Subnet Calculator

IPv4 chart includes cidr, subnet mask, wildcard and IPv6 chart includes number of /48, /56, /64, /127 per prefix Jul 17, 2005 · In this case, the netmask of 255.255.255.248 represents 29 bits of network and 3 bits of host (totalling 32 bits, of course), and this give 8 possible IP addresses in this range. The first and last of the range are reserved addresses, giving 6 usable addresses that may be assigned to a device.
Using the cheat sheet, find the exponent of 2 that is equal to or greater than the number of subnets we require (900). We can quickly see that 10 additional subnet bits will give us 1,024 subnets. Make note of the corresponding subnet mask. In this case, 255.255.255.192.
