On most operating systems localhost is the internal network address of the 
local computer. It usually lives at ip in IPv4 and ::1 in IPv6. Your 
router is probably running some form of Linux (most do), so you inherit the 
standard Linux localhost. (Actually, in IPv4, any address starting with 127 
will resolve to localhost.)

The localhost address is used internally by the operating system to talk to 
itself via what’s called the loopback interface.
