IP addresses are assigned to a host either dynamically as they join the network, or persistently by configuration of the host hardware or software. Persistent configuration is also known as using a static IP address. In contrast, when a computer's IP address is assigned each time it restarts, this is known as using a dynamic IP address.
Network diagram with IP network addresses indicated e.g. 192.168.100.3.. A network address is an identifier for a node or host on a telecommunications network.Network addresses are designed to be unique identifiers across the network, although some networks allow for local, private addresses, or locally administered addresses that may not be unique.

The IP address in CIDR notation is always represented according to the standards for IPv4 or IPv6. The address may denote a specific interface address (including a host identifier, such as 10.0.0.1 / 8 ), or it may be the beginning address of an entire network (using a host identifier of 0, as in 10.0.0.0 / 8 or its equivalent 10 / 8 ).
Some commercial databases have augmented geolocation software with demographic data to enable demographic-type targeting using IP address data. The primary source for IP address data is the regional Internet registries which allocates and distributes IP addresses amongst organizations located in their respective service regions:
An IP packet is the smallest message entity exchanged via the Internet Protocol across an IP network. IP packets consist of a header for addressing and routing, and a payload for user data. The header contains information about IP version, source IP address , destination IP address, time-to-live , etc.
IP address, a numerical label assigned to each device connected to a computer network; IP (complexity), a class in computational complexity theory; IP core (intellectual property core), a reusable design unit owned by one party; Instruction pointer, a processor register; Intelligent Peripheral, a part of a public telecommunications Intelligent ...
However, IP addresses should almost never be indefinitely blocked. Many IP addresses are dynamically assigned and change frequently from one person to the next, and even static IP addresses are periodically reassigned or have different users. In cases of long-term vandalism from an IP address, consider blocks over a period of months or years ...
Dual-stack IP implementations provide complete IPv4 and IPv6 protocol stacks in the operating system of a computer or network device on top of the common physical layer implementation, such as Ethernet. This permits dual-stack hosts to participate in IPv6 and IPv4 networks simultaneously.
