We all know that 127.0.0.1 points to localhost.
However, have you ever wondered why 127.0.0.1 IP Address is assigned to localhost?
Why Is Localhosts IP Address 127.0.0.1?
How does It work?
In the computer world, localhost refers to the location of the system being used.
You also might be knowing that 127.0.0.1 points to localhost.
However, have you ever wondered why localhosts IP address is 127.0.0.1 why not something else?
The address 127.0.0.1 is used to establish a connection to the same computer used by the end-user.
127.0.0.1 is the first assignable address in the subnet.
127.0.0.0 cannot be used because that would be the wire number.
But using any other numbers for the host portion should work fine and revert to using127.0.0.1.
you’re able to try pinging 127.1.1.1 if youd like.
Why they waited until the last web link number to implement this?
I dont think its documented.
Actually, Developers practice 127.0.0.1 to test their applications before deploying it.
Now you might be thinking why localhost IP address starts with 127?
127.0.0.1 is the first assignable address in the subnet.
Therefore, any number from the host portion will work fine.
you’re free to try pinging 127.1.0.1, you will be looped back to your own machine.
Actually, the earliest mention of 127 as loopback dates back to November 1986 RFC 990.
Some might think that it could be more sensible to choose 1.0.0.0 for loopback.
However, that was already given to BBC Packet Radio data pipe.
