Ip address

From TinWiki.org

An IP address is a numerical address assigned to an electronic device on a TCP/IP network. An IP address acts a locator for one IP address to find another network IP device. It does not intended to indentify a device all of the time due to dynamic assignment and (NAT) Network Address Translation.

The (IANA) Internet Assigned Numbers Authority manages and assigns public IP Addresses.

Numbering Scheme

There are four numbers in an IPv4 address, which is currently in use. (0.0.0.0)

IPv4 uses 32-bit addresses. IPv4 addresses are represented in dotted-decimial notation (four numbers each ranging from 0 to 255, separated by dots. (192.182.29.120)

IPv4 uses 128-bit addresses. IPv6 addresses are represented by netblocks. Example: 2839:8db8:85a3:28d3:1319:8a2e:0370:3821

There are also three classes.

- Class A - supports 16 million hosts on each of 126 networks
- Class B - supports 65,000 hosts on each of 16,000 networks
- Class C - supports 254 hosts on each of 2 million networks

Unassigned IP addresses are running out, so a new system is being implemented called CIDR.

Static & Dynamic IP Addresses

There are static & dymanic IP addresses that are utiliezed currently.

Static IP addresses are manually assigned by network administrators either through the operating system or command-line. Static IP addresses are usually utilized if a device needs to be accessed remotely.

Dynamic IP addresses are assigned by (DHCP) Dynamic Host Configuration Protocol servers. Use of these servers are a way of assigning IP address without a network administrator assigning IP addresses to each individual networked device.
