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 .
127.0.0.0/8 127.0.0.0–127.255.255.255 16 777 216: Host Used for loopback addresses to the local host [1] 169.254.0.0/16 169.254.0.0–169.254.255.255 65 536: Subnet Used for link-local addresses [5] between two hosts on a single link when no IP address is otherwise specified, such as would have normally been retrieved from a DHCP server 172 ...
How private is my IP address? It depends. The operators of any website that you visit can see it. If you are not logged into Wikipedia, your IP address is publicly recorded with every edit that you make. If you are logged in, your IP address is hidden from all but a very small number of trusted administrators. In some cases, it is possible that ...
This means that 256 /8 address blocks fit into the entire IPv4 space. As IPv4 address exhaustion has advanced to its final stages, some organizations, such as Stanford University, formerly using 36.0.0.0 / 8, have returned their allocated blocks (in this case to APNIC) to assist in the delay of the exhaustion date.
Transmission is handled similarly; established sockets may be used to transmit IPv4 or IPv6 datagram, based on the binding to an IPv6 address, or an IPv4-mapped address.::ffff:0:0:0 / 96 — A prefix used for IPv4-translated addresses. These are used by the Stateless IP/ICMP Translation (SIIT) protocol. [40] 64:ff9b:: / 96 — The well-known ...

In IPv6, the same result is achieved by sending a packet to the link-local all nodes multicast group at address ff02::1, which is analogous to IPv4 multicasting to address 224.0.0.1. IPv6 also provides for new multicast implementations, including embedding rendezvous point addresses in an IPv6 multicast group address, which simplifies the ...
The Internet Engineering Task Force (IETF) has reserved the IPv4 address block 169.254.0.0 / 16 (169.254.0.0 – 169.254.255.255) for link-local addressing. [1] The entire range may be used for this purpose, except for the first 256 and last 256 addresses (169.254.0.0 / 24 and 169.254.255.0 / 24), which are reserved for future use and must not be selected by a host using this dynamic ...
