How is maximum host calculated?

To find the maximum number of hosts, look at the number of binary bits in the host number above. The easiest way to do this is to subtract the netmask length from 32 (number of bits in an IPv4 address). This gives you the number of host bits in the address.

How is Network mask calculated?

The first and last addresses are reserved: the first to identify the network and the last to be used as the broadcast address.

1. Find host range.
2. Convert to binary.
3. Calculate the total number of hosts per subnet.
4. Calculate the number of subnets.
5. Verify the total number of subnets.

How is host range calculated?

To calculate the number of possible hosts per subnet, use the formula 2h – 2, where h equals the number of host bits. The reason two addresses must be subtracted is because of the network address and the broadcast address.

How to use IPIP subnet calculator?

IP Subnet Calculator tool divides a given IP Address network into the subnetworks by calculating the useful information like a network address, subnet mask, broadcast address, and host IP Address. You have to enter the IP Address and Subnet Mask, and this tool instantly calculates the required information for your use.

What information does this calculator return about IPv4 and IPv6 subnets?

This calculator returns a variety of information regarding Internet Protocol version 4 (IPv4) and IPv6 subnets including possible network addresses, usable host ranges, subnet mask, and IP class, among others.

How do I use ipcalc?

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. Enter your netmask(s)…

How do I find the host part of an IP address?

Enter your netmask (s) in CIDR notation (/25) or dotted decimals (255.255.255.0). Inverse netmasks are recognized. If you omit the netmask ipcalc uses the default netmask for the class of your network. Look at the space between the bits of the addresses: The bits before it are the network part of the address, the bits after it are the host part.
