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

Question

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. 12 сент. 2011 г.

What is the :: 1 address?

::1 is the loopback address in IPv6. Think of it as the IPv6 version of 127.0. 0.1 .

Is localhost and 127.0 0.1 the same?

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 127.0 1.1 IP address called?

Each device has it's own localhost . 127.0. 1.1 on the other hand is used by certain software to mean the same thing, an alias in a way, but not really. The loopback address used by your machine internally should be 127.0.

What is the difference between 127.0 0.1 and IP address?

As for the 127.0. 0.1 address, that is what is called a “loopback” address - it is a special IP address that you can send traffic to that will just go right back to yourself. As you mentioned, on a typical computer, 127.0. 0.1 is the same as localhost.
