Which three IP addresses can be assigned to hosts of the subnet mask is 27?

Which three IP addresses can be assigned to hosts of the subnet mask is 27?

Explanation: If you follow the cram table, /27 is mask 255.255. 255.224.

Is 0 a valid subnet mask?

0.0, the resulting subnet mask, the corresponding broadcast addresses, and the range of valid host addresses. In the example above, the first subnet (subnet 172.16. 0.0/19) is called subnet zero. Subnet zero is also known as the all-zeros subnet.

What does subnet mask 0 mean?

A subnet mask is a 32-bit number created by setting host bits to all 0s and setting network bits to all 1s. In this way, the subnet mask separates the IP address into the network and host addresses. The “255” address is always assigned to a broadcast address, and the “0” address is always assigned to a network address.

How do you use IP subnet 0?

To enable the use of subnet zero for interface addresses and routing updates, use the ip subnet-zero global configuration command. To restore the default, use the no form of this command.

Can an IP address end in zero?

in general statement ‘IP addresses ending in . 0 or . 255 is invalid’ is false.

Can an IP address end in 1?

As a convention, an IP address that ends in “. 1” usually refers to a gateway or router on a particular network. An address that ends in “. 255” is a so-called broadcast address: all devices in the same network should handle packets addressed to the broadcast address.

Why do we need subnet mask?

A subnet mask is used to divide an IP address into two parts. One part identifies the host (computer), the other part identifies the network to which it belongs. To better understand how IP addresses and subnet masks work, look at an IP address and see how it’s organized.

How do you subnet an IP address?

255.248 or /29.

  1. Step 1: Convert to Binary.
  2. Step 2: Calculate the Subnet Address. To calculate the IP Address Subnet you need to perform a bit-wise AND operation (1+1=1, 1+0 or 0+1 =0, 0+0=0) on the host IP address and subnet mask.
  3. Step 3: Find Host Range.
  4. Step 4: Calculate the Total Number of Subnets and.

What is 23 subnet?

/ 21 2048 255.255.248.0

When is a subnet mask part of the network?

Whenever a bit in a binary subnet mask is 1, then the same bit in a binary IP address is part of the network, not the host. Since the octet 255 is 11111111 in binary, that whole octet in the IP address is part of the network. So the first three octets, 192.168.0, is the network portion of the IP address, and 101 is the host portion.

When to use subnet zero and all-one addresses?

The -2 takes into account that subnet zero and the all-ones subnet are not used traditionally. Using subnet zero for addressing was discouraged because of the confusion inherent in having a network and a subnet with indistinguishable addresses. With reference to our example above, consider the IP address 172.16.1.10.

Is there an IPv4 subnet mask calculator?

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.
