What Is An IP Address?

If you have a device or computer and connect to the Internet it will always involving have an IP address.

IP Address (Internet Protocol Address)

This number is an exclusive number on all information technology devices (printers, routers, modems, etc) use which identifies and allows them the ability to communicate with each other on a computer network.

Moreover, there is a standard of communication which is called an Internet Protocol (IP) standard. To clarify, in layman's terms it is the same as your home address. Therefore, in order for you to receive snail mail at home the sending party must have your correct mailing address (Internet Protocol address) in your town (network) or you do not receive bills, pizza coupons or your tax refund. The same is true for all equipment on the internet.  However, there are exclusions of the information without this specific address.  Consequently, IP addresses assigned permanently for an Email server/Business server or a permanent home resident.   Or even temporarily, from a pool of available addresses (first come first serve) from your Internet Service Provider. A permanent number may not be available in all areas and may cost extra so be sure to ask your ISP.

Domain Name System (DNS): The Internet Protocol address translated to words.  It is much easier for us to remember a word than a series of numbers. The same is true for email addresses.
For example, it is much easier for you to remember a web address name such as whatismyip.com than it is to remember or in the case of email it is much easier to remember [email protected] than [email protected]

Different IP Addresses

Dynamic IP Address: An IP address that is not static and could change at any time. This IP address issued to you from a pool of IP addresses allocated by your ISP or DHCP Server.  This is for a large number of customers that do not require the same IP Address all the time for a variety of reasons. However, your computer will automatically get this number as it logs on to the network and saves you the trouble of having to know details regarding the specific network configurations.  Assignment of this number to anyone using dial-up connection, wireless and high speed internet connections. If you need to run your own email server or web server, it would be best to have a static IP.

Static IP Address: An IP address that never changes and fixed.  This is in contrast to a dynamic IP address which may change at any time. Most ISP's have a single static IP or a block of static IP's for a few extra bucks a month.

Older and Current IP versions

IP version 4: Currently used by most network devices. However, with more and more computers accessing the internet, IPv4 addresses are running out quickly. Just like in a city, addresses have are created for new neighborhoods.  However, if your neighborhood gets too large, you will have to come up with an entire new pool of addresses. IPv4 limited to 4,294,967,296 addresses.

IP version 5: This is an experimental protocol for UNIX based systems. In keeping with standard UNIX (a computer Operating System) release conventions, all odd-numbered versions considered experimental.  These were never intended for the general public.

IP version 6: The replacement for the aging IPv4. The estimated number of unique addresses for IPv6 is 340,282,366,920,938,463,463,374,607,431,768,211,456 or 2^128.

The old and current standard of addresses was this:  The new way written different ways but means the same and are all valid:

1) * 1080:0000:0000:0000:0000:0034:0000:417A

2) * 1080:0:0:0:0:34:0:417A

3) * 1080::34:0:417A
