# How do you calculate subnet range?

## How do you calculate subnet range?

The number of subnets is found by counting the number of bits by which the initial mask was extended, also known as the subnet bits. Our initial address allocation was 192.168. 0.0 with a mask of 255.255. 0.0.

## How many host addresses are available in 128 network?

This means that Class A addressing can have a total of 128 (27) networks and 16,777,214 (224-2) usable addresses per network. Also, note that the range 127.0. 0.0 to 127.255. 255.255 within the Class A range is reserved for host loopback address (see RFC5735).

What is an IP calculator?

An IP subnet calculator is a tool, normally an online tool, which performs a series of calculations based on specific values and returns the results. Network, in IP/Netmask form. Network mask. Network wildcard, or part of the usable IP addresses. Network address, the IP of the network itself.

### How is host range calculated?

The host range will start from the next address after the subnet address for example for the subnet 192.168. 116.32/27 the host range will start at 192.168. 116.33 and end at one less the broadcast address which will be 192.168. 116.62 since the broadcast address is 192.168.

### How do I calculate subnet mask from IP range?

## What is network calculator?

It is a tool for calculating the subnets. Basically, you give the Subnet Calculator a range of IP addresses or CIDR notations and it calculates/generates a list of subnets for you. Subnet is a “Sub Net” which can also be thought of as a partitioned portion of a network.

What does host range mean in network calculator?

HOST RANGE Shows the range of IP address belonging to the network, which can be configured as hosts.

### When to use the IP address and range calculator?

IP Address & Range Calculator Use this calculator if you have a list of IP addresses or IP ranges you want to sort, deduplicate, or ensure that another set of IP ranges is excluded (e.g. whitelist / blacklist). The calculator will evaluate the shortest possible representation of the these IP addresses as network blocks.

### How does the IP subnet mask calculator work?

The IP Subnet Calculator performs subnet calculations for the given network address block, subnet mask, maximum required hosts per subnet and determines the resulting broadcast address, subnet, Cisco wildcard mask and host range.

How to calculate the IP address of a Cisco router?

The Cisco wildcard mask is the inverted network mask used in Cisco routers for access control lists (ACLs). To calculate an enter the IP address, choose a prefix length and click “Get IP Info”.
