It contains common IPv4 netmasks expressed in four different formats. 1.5. Understanding CIDR Subnet Mask Notation

Addresses Hosts Netmask Amount of a Class C / 30: 4: 2: 255.255.255.252: 1 / 64 / 29: 8: 6: 255.255.255.248: 1 / 32 / 28: 16: 14: 255.255.255.240: 1 / 16 / 27: 32: 30 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. Jun 07, 2019 · A netmask is a 32-bit binary mask used to divide an IP address into subnets and specify the network's available hosts.. In a netmask, two of the possible addresses, represented as the final byte, are always pre-assigned and unavailable for custom assignment.
IP Subnet Calculator . The IP Subnet Mask Calculator enables subnet network calculations using network class, IP address, subnet mask, subnet bits, mask bits, maximum required IP subnets and maximum required hosts per subnet. Results of the subnet calculation provide the hexadecimal IP address, the wildcard mask, for use with ACL (Access Control Lists), subnet ID, broadcast address, the subnet
