What is the difference between localhost and localhost?

What is localhost and local server?

In computer networking, localhost is a hostname that refers to the current device used to access it. It is used to access the network services that are running on the host via the loopback network interface. Using the loopback interface bypasses any local network interface hardware.

Should I use 127.0 0.1 or localhost?

On most machines localhost and 127.0. 0.1 are functionally identical. But localhost is a label for the IP address and not the address itself. Localhost could be pointed at different IP addresses.

What is the difference between 127.0 0.1 and :: 1?

On modern computer systems, localhost as a hostname translates to an IPv4 address in the 127.0. 0.0/8 (loopback) net block, usually 127.0. 0.1, or ::1 in IPv6. The only difference is that it would be looking up in the DNS for the system what localhost resolves to.

What is my local host?

Localhost is a hostname that refers to the local machine currently making the request. On many computers, localhost is an alias for the IP address 127.0. 0.1. When a computer pings this IP address, it is communicating with itself.
