Hello, i just wanna to share all of you about how to check IP address. Actually, there a lot of way how we can detect our IP Address.
Introduction.
What is IP address?
Every device connected to the public Internet is assigned a unique number known as an Internet Protocol (IP) address. IP addresses consist of four numbers separated by periods (also called a 'dotted-quad') and look something like 127.0.0.1.
Since these numbers are usually assigned to internet service providers within region-based blocks, an IP address can often be used to identify the region or country from which a computer is connecting to the Internet. An IP address can sometimes be used to show the user's general location.
Types of IP addresses
There are two types of IP addresses: Static and Dynamic. When the IP address of a computer remains the same every time it connects to the network, then it is called a Static IP address. However, when the IP address of a computer changes every time it connects to the network, it is referred to as a Dynamic IP address.
Domain Name System (DNS): This allows the IP address to be 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 192.168.1.1 or in the case of email it is much easier to remember email@somedomain.com than email@192.168.1.1
Dynamic IP: One that is not static and could change at any time. This type of IP is 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 all the time for a variety of reasons. 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. This number can be assigned to anyone using a 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: One that is fixed and never changes. This is in contrast to a dynamic IP which may change at any time. Most ISP's a single static IP or a block of static IP's for a few extra bucks a month.
IP version 4: Currently used by most network devices. However, with more and more computers accessing the internet, IPv4 IPs are running out quickly. Just like in a city, addresses have to be created for new neighborhoods but, if your neighborhood gets too large, you will have to come up with an entire new pool of addresses. IPv4 is limited to 4,294,967,296 IPs.
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 are considered experimental. It was never intended to be used by the general public.
IP version 6: The replacement for the aging IPv4. The estimated number of unique IPs 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 IPs was this: 192.168.100.100 the new way can be written different ways but means the same and are all valid:
* 1080:0000:0000:0000:0000:0034:0000:417A
* 1080:0:0:0:0:34:0:417A
* 1080::34:0:417A

Other method to find IP address.
If you want to find an IP address of your computer (if you are running Windows) then the process is quite simple:
- Click on the ‘Start’ menu button on the Windows taskbar.
- Click ‘Run’.
- In the text box, type ‘cmd’. This will launch a command prompt menu.
- In this menu, type ‘ipconfig/all’.
You will find your computer’s IP address in the IP address field.
Detect IP address in received e-mail:
If you want to detect IP address of the computer from which you have received an e-mail, you can find it in the e-mail header. Usually, this information is disabled from viewing. If you click on ‘Show Headers’ while viewing your e-mail on the Internet, you will be able to see the IP address of the computer from where the e-mail was sent.
Some Uses of IP addresses
IP addresses are also useful for detecting and solving cyber crimes and Internet based frauds and thefts such as phishing. They are also useful to track down spam or unsolicited e-mail, or when you have received malicious e-mails or e-mail threats and viruses via e-mail.
