Hello tadpole1604-ga
Thank-you for your question.
127.0.0.1 is set aside for your host computer (the one you are using).
This is often called "localhost". It allows your computer to route
packets by TCP/IP to itself.
"What is "local host"? What is 127.0.0.1?
The IP address 127.0.0.1 is a reserved IP address specified in the
Internet Protocol used to represent the host computer, whichever
computer you happen to be sitting in front of with TCP/IP
capabilities. This is often necessary as a background way for TCP/IP
to route packets from the host to itself. But it is often used as a
simple troubleshooting procedure. You can send data to and from
yourself to test the installation of TCP/IP. Type "ping 127.0.0.1"
from a command prompt. If you get no response, or "destination host
unreachable", it's time to reinstall TCP/IP. If you get responses,
they should show extremely low ping times, like 0.1ms or less. (TCP/IP
may still need to be reinstalled, if it's not possible to ping
elsewhere.)"

"What is 127.0.0.1?
127.0.0.1 is a loopback network connection. This means that if you
try to connect to 127.0.0.1, you are immediately looped back to your
own machone. In other words, 127.0.0.1 is you. localhost is another
name for 127.0.0.1."

"In computing the term localhost refers to the location of the
currently used system. It is a loopback device which is assigned the
IP address 127.0.0.1 in IPv4, or ::1 in IPv6, which can be used by
TCP/IP applications to talk to themselves if this is needed. If you
are running a server, localhost will most likely open a page."
