Network calculator or IP Subnet Mask Calculator is a network service used to Calculates subnet range by network mask. This service calculate subnet network IP address using network class, IP地址, 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 address range for the resulting subnet network and a subnet bitmap.

Enter your netmask(s) in CIDR notation (/25) or dotted decimals (255.255.255.0). Inverse netmasks are diagnosed. in case you miss the netmask ipcalc makes use of the default netmask for the class of your community.

Have a look at the space 其中 the bits of the addresses: The bits 早於 it are the network a part of the deal with, the bits after it are the host component. you could see two simple statistics: In a community address all host bits are 0, in a published cope with they’re ready.

The magnificence of your communitydecided through its first bits.

In case your community is a private 互聯網 in line with RFC 1918 this is remarked. while displaying subnets the brand new bits 在 - 的里面 network part of the netmask are marked in a distinct color
