What is loopback and broadcast address?
Any traffic that a computer program sends on the loopback network is addressed to the same computer. The most commonly used IP address on the loopback network is 127.0. 0.1 for IPv4 and ::1 for IPv6. The standard domain name for the address is localhost. A network device also includes an internal loopback address (lo0.
What is the difference between 127.0 0.1 and localhost?
On most machines localhost and 127.0. 0.1 are functionally identical. But localhost is a label for the IP address and not the address itself. Localhost could be pointed at different IP addresses.
What is a valid local loopback address?
Local Loopback Address: Typically 127.0. 0.1 is used as the local loopback address. This leads to the wastage of many potential IP addresses. But in IPv6 ::1 is used as local loopback address and therefore there isn’t any wastage of addresses.

What’s the difference between host and network IP addresses?
The first IP address is usually reserved for the Network address and the last one in that block is for the Broadcast address, while the remaining ones can be used as Host addresses. Loopback address is a special reserved IP address, usually referred to as the localhost – 127.0.0.1 and is used to communicate with the localhost.
When do you use a local broadcast address?
Local Broadcast Address is used to communicate with all the devices on a local network. It is represented by 255.255.255.255 or 11111111.11111111.11111111.11111111 in binary. A broadcast address is used by hosts to request IP addresses from the DHCP (Dynamic Host Configuration Protocol) server.
Where do you find the host and network addresses?
You can arrive at these addresses by performing an logical AND on the IP address and the Subnet Mask. The first IP address is usually reserved for the Network address and the last one in that block is for the Broadcast address, while the remaining ones can be used as Host addresses.
