IP Address

An IP handle, or just an “IP,” is a singular handle that identifies a tool on the Internet or a native network. It permits a system to be acknowledged by different programs linked by way of the Internet protocol. There are two major varieties of IP handle codecs used right now — IPv4 and IPv6.

IPv4

An IPv4 handle consists of 4 units of numbers from 0 to 255, separated by three dots. For instance, the IP handle of TechTerms.com is 67.43.14.98. This quantity is used to establish the TechTerms web site on the Internet. When you go to http://thowtofixissue.com in your internet browser, the DNS system routinely interprets the domain identify “thowtofixissue.com” to the IP handle “67.43.14.98.”

There are three lessons of IPv4 handle units that may be registered by way of the InterNIC. The smallest is Class C, which consists of 256 IP addresses (e.g., 123.123.123.xxx — the place xxx is 0 to 255). The next largest is Class B, which accommodates 65,536 IP addresses (e.g. 123.123.xxx.xxx). The largest block is Class A, which accommodates 16,777,216 IP addresses (e.g. 123.xxx.xxx.xxx).

The complete variety of IPv4 addresses ranges from 000.000.000.000 to 255.255.255.255. Because 256 = 2⁸, there are 2^{8 x 4} or 4,294,967,296 doable IP addresses. While this may occasionally look like a big quantity, it’s not sufficient to cowl all of the units linked to the Internet around the globe. Therefore, many units now use IPv6 addresses.

IPv6

The IPv6 handle format is far totally different than the IPv4 format. It accommodates eight units of 4 hexadecimal digits and makes use of colons to separate every block. An instance of an IPv6 handle is: 2602:0445:0000:0000:a93e:5ca7:81e2:5f9d. There are 3.4 x 10³⁸ or 340 undecillion) doable IPv6 addresses, that means we should not run out of IPv6 addresses anytime quickly.
