IP Address Presented by Ravi Namboori

IP Address IP Address is a numerical number assigned to each and every device which is looped in a computer network that uses the Internet Protocol for communication. We are having two versions in ip address. They are: Ip version 4 (IPV4) Ip version 6 (IPV6) Ip version 4 is represented by (length) 32 bit addressing.it contains only zeros and ones (0's & 1's). Ip version 6 is represented by 128 bits addressing.it contains only numbers and letters.

Basic IP Adderssing  Machines read the IP address as a stream of 32 bits.  However, for human consumption, the IP address is written in dotted decimal notation. The 32-bit address is divided into 4 groups of 8 bits (an octet or a byte). Each octet is written as a decimal number ranging from 0 to 255. The decimal numbers are separated by periods, or dots.

IP Address Stricture The network prefix identifies a network and the host number identifies a specific host (actually, interface on the network).

Address Space Address space is the amount of memory allocated for all possible addresses for a computational entity, such as a device, a file, a server, or a networked computer. Address space may refer to a range of either physical or virtual addresses accessible to a processor or reserved for a process. As unique identifiers of single entities, each address specifies an entity's location. On a computer, each computer device and process is allocated address space, which is some portion of the processor's address space. A processor's address space is always limited by the width of its address bus and registers. Address space may be differentiated as either flat, in which addresses are expressed as incrementally increasing integers starting at zero, orsegmented, in which addresses are expressed as separate segments augmented by offsetsbusregister

IN IP ADDRESSES WE HAVE 5 CLASSE THEY ARE : Class A Class B Class C Class D Class E In these classes class A, B, C are using for local area networks and wide area networks. & remaining class D for multicasting networks and class E for Research and development. These class are defined in ranges as follows : Class A : to Class B : to Class C : to Class D : to Class E : to

Types OF IP Addresses Public Address Private Address Public Addresses: Public addresses are registered as belonging to a specific organization. Public IP addresses are routed across the Internet, so that hosts with public addresses may freely communicate with one another globally. Private Addresses: Private addresses may be used by any organization, without any requirement for registration. – private addresses are not permitted to be routed across the Internet.
