An IP address is a unique address that identifies a device on the internet or a local network. IP stands for "Internet Protocol," which is the set of rules governing the format of data sent via the internet or local network. In essence, IP addresses are the identifier that allows information to be sent between devices on a network: they contain location information and make devices accessible for communication.

IPv4 Private Address Space and Filtering

All IPv4 addresses can be divided into two major groups: global or public, external - this group can also be called 'WAN addresses' — those that are used on the Internet, and private or local, internal addresses — those that are used in the local network LAN. These are public global addresses that are used on the Internet. Public IP addresses can be routed on the Internet, unlike private addresses. Note: All servers and sites on the Internet use public IP addresses for example, google. All of the public IP-addresses on the Internet are unique to their host or server and cannot duplicate. Due to the limited number of public IP addresses and the increasing number of Internet users, ISPs are now more common to give private IP addresses to subscribers.

Private network

An IP address internet protocol address is a numerical representation that uniquely identifies a specific interface on the network. Addresses in IPv4 are bits long. This allows for a maximum of 4,,, 2 32 unique addresses. Addresses in IPv6 are bits, which allows for 3. The total usable address pool of both versions is reduced by various reserved addresses and other considerations. IP addresses are binary numbers but are typically expressed in decimal form IPv4 or hexadecimal form IPv6 to make reading and using them easier for humans. IP stands for Internet Protocol and describes a set of standards and requirements for creating and transmitting data packets, or datagrams, across networks.

Like postal address used to deliver a postal mail to your home, a public IP address is the globally unique IP address assigned to a computing device. Private IP address, on the other hand, is used to assign computers within your private space without letting them directly expose to the Internet. For example, if you have multiple computers within your home you may want to use private IP addresses to address each computer within your home. In this scenario, your router gets the public IP address, and each of the computers, tablets and smartphones connected to your router via wired or wifi gets a private IP address from your router via DHCP protocol. The following IP blocks are reserved for private IP addresses. A public IP address is the address that is assigned to a computing device to allow direct access over the Internet.

IPv4 addresses are bit numbers that are typically displayed in dotted decimal notation. A bit address contains two primary parts: the network prefix and the host number.

In IP networking , a private network is a computer network that uses private IP address space. Private network addresses are not allocated to any specific organization. Anyone may use these addresses without approval from regional or local Internet registries. Private IP address spaces were originally defined to assist in delaying IPv4 address exhaustion.
