Can the loopback address be pinged if your computer does not have an IP address?
Yes, you can. In the PC world, 127.0. 0.1 is the “loopback” address.
Can you ping a loopback address?

- Specify the loopback interface IP address or host name.
- Click Ping Now to send the Ping.
Which address can be used to ping the loopback interface?
127.0.0.1
A loopback address is a special IP address, 127.0. 0.1, reserved by InterNIC for use in testing network cards. This IP address corresponds to the software loopback interface of the network card, which does not have hardware associated with it, and does not require a physical connection to a network.
What is the IP loopback address?
The Internet Protocol (IP) specifies a loopback network with the (IPv4) address 127.0. 0.0/8. Most IP implementations support a loopback interface (lo0) to represent the loopback facility. Any traffic that a computer program sends on the loopback network is addressed to the same computer.
What is the use of loopback IP address?
The IP address 127.0. 0.1 is called a loopback address. Packets sent to this address never reach the network but are looped through the network interface card only. This can be used for diagnostic purposes to verify that the internal path through the TCP/IP protocols is working.

What’s the difference between positive reply and pinging loopback?
Both methods are IP addressing troubleshooting steps. As first step, I’m pinging loopback (127.0.0.1) address. Positive reply means IP stack is initialized on my host. Then I’m pinging local address. Positive reply means my network interface controller (NIC) is functioning.
When do you Ping your IP address, you are pinging yourself?
A different network card. When you ping the loopback, you are pinging yourself, and there is somewhere (where varies from system to system, slightly) something representing a network interface on yourself. When you ping your IP address, you ping yourself, but it goes through those drivers for that network card first, or at least can.
