What Is the Difference between IPV4 and IPV6 Format?


IPV4 formatting is the formatting you might already be familiar with - To break this down further in developer-speak: A valid IPV4 formatted address must contain four integers separated by periods, and each of these numbers must be greater than -1 and less than 225;

The acronym IPV4 stands for "Internet Protocol Version 4," which means it was the fourth version formulated by network masterminds to define how hosts and devices (i.e. your PC) should be identified with one another. A fundamental problem with the IPV4 format, however, is the limited number of addresses that can be used. Hence, IPV6 was invented to provide a huge range of available addresses.

IPV6 stands for "Internet Protocol Version 6" because the design was finalized two versions after IPV4. Here is an example of an IPV6 Address:

• "AD82:0000:0000:0000:0444:C31E:AB1F:2584"

Notice that there are are 8 sections, or 16 bit blocks, for a total of 128 bits.
