What is the difference between 127.0 0.1 and IP address?

Question

The loopback address is only used by the computer you're on, and only for special circumstances—unlike a regular IP address that transfers files to and from other networked devices. For example, a web server running on a computer can point to 127.0. 0.1 so that the pages run locally and test before it's deployed. 15 янв. 2022 г.

What is the 127.0 0.1 IP address and what is it used for?

The address 127.0. 0.1 is the standard address for IPv4 loopback traffic; the rest are not supported by all operating systems. However, they can be used to set up multiple server applications on the host, all listening on the same port number.

What is 127.0 0.1 that is a special IP address called?

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 is the IP address 127.0 0.2 used for?

0.0/8 - This block is assigned for use as the Internet host loopback address. A datagram sent by a higher-level protocol to an address anywhere within this block loops back inside the host. This is ordinarily implemented using only 127.0. 0.1/32 for loopback.

What does ping 127.0 0.1 tell you?

127.0. 0.1 is your local host address, and pinging it verifies whether the TCP/IP protocol is installed and functioning properly. If you cannot complete this ping, you can reconfigure your TCP/IP protocol or refer to your operating system documentation for more information.
