Loopback IP address is managed entirely by and within the operating system. These addresses enable the Server and Client processes on a single system to communicate with each other. When a process creates a packet with destination address as loopback address, the operating system loops it back ...
the Internet Protocol system has been retrenched to allow for a greater number of IP addresses. In the old IPv4 system, the loopback address was 127.0. 0.1. The syntax of the new loopback address in IPv6 is simpler: it's ::1.
Learn what is an IP address and as a unique number identifies any device that connects to the internet. Discover how IP addresses work and what IP addresses are available.
If a packet is sent to the public address by a computer at 192.168.2.3, the packet would normally be routed to the default gateway (the router), unless an explicit route is set in the computer's routing tables. A router with the NAT loopback feature detects that 202.96.128.5 is the ad...

127.0.0.1: This is called the loopback address, meaning your computer's way of identifying itself, whether or not it has an assigned IP address. 169.254.0.1 to 169.254.255.254: This is the Automatic Private IP Addressing (APIPA) range of addresses assigned automatically when a computer's unsu...
If no loopback interface is configured, the router selects the largest IP address among other interface addresses as its router ID. After the router has been running OSPF and selected its router ID, it still uses this router ID if the interface whose IP address is used as the router ID ...
By default, OSPF advertises the IP address of the loopback interface as a 32-bit host route, which is irrelevant to the mask length configured on the loopback interface. To advertise routes to the network segment of the loopback interface, configure the network type as NBMA or broadcast in...
RFC 1918allows for the following private address ranges (which can be either static or dynamic): 10.0.0.0/8 (such as 10.1.1.10) 172.16.0.0/12 (such as 172.16.0.10 but never 172.0.0.0 because those addresses are reserved for what's calledloopback) ...
Host Scope: The loopback address 0:0:0:0:0:0:0: can use a host to send IPv6 datagrams to itself. Link Local Scope: For IPv6 connectivity, is it essential that each host has its own address, even if it is only valid on a local network. This link local address is identified by...
