IP history
Its development began in 1974, led by reckoner scientists Bob Kahn and Vint Cerf. It is often used in conjunction with the Manual Control Protocol, or TCP. Together they are referred to as TCP/IP.
The get-go major version of the Net Protocol was version four, or IPv4. In 1981, it was formally defined in RFC 791 by the Net Technology Task Force, or IETF.
The successor to IPv4 is IPv6, which was formalized by the IETF in 1998. It was designed to somewhen supervene upon IPv4. As of 2018, IPv6 governs approximately 20% of all Internet traffic.
IP addresses
An IP address is a number identifying of a estimator or another device on the Net. It is like to a mailing address, which identifies where postal post comes from and where it should be delivered. IP addresses uniquely identify the source and destination of information transmitted with the Net Protocol.
IPv4 and IPv6 addresses
IPv4 addresses are 32 $.25 long (four bytes). An example of an IPv4 address is 216.58.216.164, which is the front folio of Google.com.
The maximum value of a 32-bit number is 232, or 4,294,967,296. So the maximum number of IPv4 addresses, which is called its accost space, is about 4.three billion. In the 1980s, this was sufficient to address every networked device, simply scientists knew that this space would apace become exhausted. Technologies like NAT have delayed the problem by allowing many devices to use a single IP accost, merely a larger address infinite is needed to serve the modern Internet.
A major reward of IPv6 is that information technology uses 128 $.25 of data to store an address, permitting 2128 unique addresses, or 340,282,366,920,938,463,463,374,607,431,768,211,456. The size of IPv6's address space — 340 duodecillion — is much, much larger than IPv4.
IP address classes
With an IPv4 IP address, there are v classes of available IP ranges: Grade A, Class B, Class C, Class D and Grade E, while simply A, B, and C are commonly used. Each class allows for a range of valid IP addresses, shown in the post-obit tabular array.
| Form | Address range | Supports |
|---|---|---|
| Grade A | 1.0.0.1 to 126.255.255.254 | Supports 16 million hosts on each of 127 networks. |
| Class B | 128.1.0.1 to 191.255.255.254 | Supports 65,000 hosts on each of 16,000 networks. |
| Class C | 192.0.1.1 to 223.255.254.254 | Supports 254 hosts on each of two million networks. |
| Class D | 224.0.0.0 to 239.255.255.255 | Reserved for multicast groups. |
| Class E | 240.0.0.0 to 254.255.255.254 | Reserved for hereafter use, or research and development purposes. |
Ranges 127.x.x.x are reserved for the loopback or localhost, for example, 127.0.0.one is the loopback address. Range 255.255.255.255 broadcasts to all hosts on the local network.
IP address breakdown
Every IPv4 accost is cleaved down into four octets (another name for bytes) that range from 0 to 255 and translated into binary to represent the actual IP address. The tabular array below looks at the IPv4 address 255.255.255.255.
| In decimal: | 255 | 255 | 255 | 255 |
| In binary: | 11111111 | 11111111 | 11111111 | 11111111 |
| In octal: | 377 | 377 | 377 | 377 |
| In hexadecimal: | FF | FF | FF | FF |
As some other example, let's break downwardly the IPv4 address 166.seventy.10.23 in the following table. The first row contains the split up octets (bytes) of the IP address, represented in decimal. In decimal representation, the rightmost digit is multiplied by 1 (x0), the second-rightmost digit is multiplied past ten (tenane), the third-rightmost is multiplied by 100 (x2), etc.
The second row of the tabular array shows the same numeric values, represented in binary. In binary, the rightmost digit is multiplied by 1 (20), the second-rightmost digit is multiplied by 2 (21), the third-rightmost digit is multiplied by 4 (22), etc.
The third row shows how the binary representation can exist converted to decimal, by converting the individual digits and adding the values. Binary digits in bold correspond to the values added.
| Decimal value: | 166 | 70 | 10 | 23 |
| Binary value: | i0i00110 | 01000eleven0 | 00001010 | 00010111 |
| Conversion: | 128+32+4+2=166 | 64+iv+ii=70 | 8+2=10 | 16+4+2+i=23 |
Static vs. dynamic IP addresses
IP addresses are assigned in two different ways. They may exist dynamically assigned (they tin change automatically) or statically assigned (they're intended not to modify, and must be changed manually). About abode networks use dynamic resource allotment. Your router uses DHCP to temporarily assign, or "lease," an IP address to your device. After a some time, this lease "expires," and the router renews your old address or assigns you a new one depending on the router configuration.
The about common default addresses assigned by dwelling routers are shown beneath.
| 192.168.1.0 | This number, called the network number, identifies the network every bit a whole, and is non assigned to a device. |
| 192.168.1.1 | The common default address assigned to the gateway device. In most home networks, the gateway is the router itself. |
| 192.168.1.2 | Another common gateway address. Or, it may exist assigned to a device on the network. |
| 192.168.1.3–254 | Assigned to devices on the network. |
| 192.168.ane.255 | The broadcast address of the network. Data sent to this address is automatically circulate to addresses 1–254. |
If you accept ever tried to change the settings on your router, you may exist familiar with the address 192.168.1.i. Commonly, this is your router'south address, if you enter this address into the accost bar of your spider web browser, y'all can open your router's configuration interface. (Your router's address may be unlike - check your transmission.)
How data is sent to an IP address on another network
The following diagram illustrates how your home calculator might obtain an IP address and ship data to an IP accost on another network.

Other Internet protocols
IP is one protocol that devices use to communicate on the Internet. Some are used in conjunction with IP, and some are used independently. Examples include SMTP, which is used to transmit e-postal service, and HTTP, which is used to transmit hypermedia.
For more data well-nigh protocols in general, see our protocol definition.
Who assigns IP addresses?
In most local or home networks, the estimator and devices on the network are assigned an internal IP addresses past the router. On the Net, IP address blocks are assigned out past ICANN to ISPs (Internet service providers) who assign yous an IP address from their assigned block of addresses.

ii. In some Unix-similar operating systems, ip is a control that sets or views data about a figurer's network configuration. It replaces the deprecated command ifconfig. For more information near how to use the ip command in Linux, see our Linux ip control reference.
3. IP is an acronym for ingress protection, which refers to a concrete device's resistance to allowing external contaminants such equally grit, h2o, and vapor, from entering the device. The measurement of this resistance is referred to as the device's IP Rating.
iv. IP is an acronym for intellectual belongings. The term refers to original ideas, documents, and technologies that were conceived, adult, and created by an private or organization. It is often used in context of the property's potential value. For instance, "the video game didn't sell well, just the game engine and characters' stories are IP that volition bring profit to the visitor for years to come."
