Location is detected based on the nearest public IP address on a device (which can be a computer, the router it is connected to, or the Internet Service Provider (ISP) the router uses). The location depends on the IP information available, but in many cases where the IP is hidden behind an ISP network address translation , the accuracy is only ...
RFC 1122 refers to 0.0.0.0 using the notation {0,0}. It prohibits this as a destination address in IPv4 and only allows it as a source address under specific circumstances. A host may use 0.0.0.0 as its own source address in IP when it has not yet been assigned an address, such as when sending the initial DHCPDISCOVER packet when using DHCP .

Examination of neighborhood Bluetooth devices. Pairing a user's IP address with the GPS location of a device that's using such an IP address. Data contributed by Internet service providers. Guesstimates from adjacent Class C range and/or gleaned from network hops. Network routing information collected to the end point of the IP address.
An Internet Protocol address (IP address) is a numerical label such as 192.0.2.1 that is assigned to a device connected to a computer network that uses the Internet Protocol for communication. [1] [2] IP addresses serve two main functions: network interface identification, and location addressing.
The address 127.0.0.1 is the standard address for IPv4 loopback traffic; the rest are not supported by all operating systems. However, they can be used to set up multiple server applications on the host, all listening on the same port number. In the IPv6 addressing architecture [3] there is only a single address assigned for loopback: ::1. The ...
Endpoint ID (EID): An EID is an IPv4 or IPv6 address used in the source and destination address fields of the first (most inner) LISP header of a packet. Egress Tunnel Router (ETR): An ETR is a device that is the tunnel endpoint; it accepts an IP packet where the destination address in the "outer" IP header is one of its own RLOCs. ETR ...
The default route in Internet Protocol Version 4 (IPv4) is designated as the zero address, 0.0.0.0 / 0 in CIDR notation. [2] Similarly, in IPv6, the default route is specified by :: / 0. The subnet mask is specified as / 0, which effectively specifies all networks and is the shortest match possible. A route lookup that does not match any other ...
