More About localhost
In a network environment, “localhost” refers to the local computer or the specific device you’re using. The IPv4 address 127.0.0.1 always corresponds to that local device. In IPv6, the localhost IP address is :1.
If you run a website locally, you can access it by entering the localhost IP address in a browser. Keep in mind that if you try to access the localhost address on a different computer, you won’t see the same data.
In most cases, the 127.0.0.1 address will return a “This site can’t be reached” error unless you’re actively using localhost to host a website.
