IP Address Validation

A Valid IP Address Must Follow The Listed Rules

There must be no leading zero (045).
There must be no more than four numbers in an IPv4 address.
Each number needs to be less than or equal to 255.
A mixture of binary notation and dotted-decimal notation is not allowed.

Examples

A valid IP Address should be in the form of : a.b.c.d where a, b, c and d are integer values ranging from 0 to 255 inclusive.

127.0.0.1 - VALID

127.255.255.255 - VALID

257.0.0.1 - INVALID

225a.0.0.1 - INVALID

What is an IP ?

An IP address, or simply an "IP", is a unique address that identifies a device on the Internet or a local network. It allows a system to be recognized by other systems connected via the Internet protocol. There are two primary types of IP address formats used today - IPv4 and IPv6.

About IPv4

An IPv4 address consist of four sets of numbers from 0 to 255, separated by three dots. For example, the IP address of TechTerms.com is 67.43.14.98. This number is used to identify the TechTerms website on the Internet. When you visit http://techterms.com in your web browser, the DNS system automatically translates the domain name "techterms.com" to the IP address "67.43.14.98." There are three classes of IPv4 address sets that can be registered through the InterNIC.

Class	Address Range	Supports
Class 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 2 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 future use, or research and development purposes.

The total number of IPv4 addresses ranges from 000.000.000.000 to 255.255.255.255. Because 256 = 28, there are 28 x 4 or 4,294,967,296 possible IP addresses. While this may seem like a large number, it is no longer enough to cover all the devices connected to the Internet around the world. Therefore, many devices now use IPv6 addresses.

About IPv6

The IPv6 address format is much different than the IPv4 format. It contains eight sets of four hexadecimal digits and uses colons to separate each block. An example of an IPv6 address is: 2602:0445:0000:0000:a93e:5ca7:81e2:5f9d. There are 3.4 x 1038 or 340 undecillion) possible IPv6 addresses, meaning we shouldn't run out of IPv6 addresses anytime soon.
