In computer networking, localhost is a hostname that refers to the current computer used to access it. The name localhost is reserved for loopback purposes. [1] It is used to access the network services that are running on the host via the loopback network interface.
Where a system (such as a modem) involves round-trip analog-to-digital processing, a distinction is made between analog loopback, where the analog signal is looped back directly, and digital loopback, where the signal is processed in the digital domain before being re-converted to an analog signal and returned to the source.
A special case of private link-local addresses is the loopback interface. These addresses are private and link-local by definition since packets never leave the host device. IPv4 reserves the entire class A address block 127.0.0.0 / 8 for use as private loopback addresses. IPv6 reserves the single address ::1.
NOTE: a RID is the highest logical (loopback) IP address configured on a router, if no logical/loopback IP address is set then the router uses the highest IP address configured on its active interfaces (e.g. 192.168.0.1 would be higher than 10.1.1.2). Usually the router with the second-highest priority number becomes the BDR.
In Solaris/OpenSolaris, the loop device is called "loopback file interface" or lofi, [2] and located at /dev/lofi/1, etc. SunOS has the configuration program lofiadm. lofi supports read-only compression and read-write encryption. Available is also a 3rd-party driver fbk (File emulates Blockdevice), for SunOS/Solaris since summer 1988. [3]
TUN and TAP in the network stack. Though both are for tunneling purposes, TUN and TAP cannot be used together because they transmit and receive packets at different layers of the network stack.
Network interface device, a device that serves as the demarcation point between a telephone carrier's local loop and the customer's wiring; Virtual network interface, an abstract virtualized representation of a computer network interface Loopback interface, a virtual network interface that connects a host to itself
