About IP Address and its types

IP Address
---------------------------------------------------
Whenever you connect to the internet, you are giving a unique 4 number Internet Protocol Address (IP Address). Your IP address is how data from your computer to a website is how data finds its way back and forth.
Your IP address may change each time you attach to your ISP. If your IP address stays the same from connection to connection, you are said to have a static IP address. If it changes each time you connect, you are said to have a Dynamic IP Address.
IP addresses can be important in the context of search engine submission because some search engines have been known to ignore submissions from any one IP over a certain limit.

Static IP Address
-----------------------------------------------
An IP address that remains constant each time a person logs on to the internet..

Dynamic IP Address
------------------------------------------------
An IP address that changes each time you connect to the internet.

Dynamic vs Static IP Address
There are two methods to assigning IP addresses to computers: dynamic and static. Static IP addresses are used primarily for servers so that they don't appear to "move" while non-servers are usually assigned dynamic IP addresses. Most dynamic IP address users are users of internet service providers (ISPs) since not all the users of an ISP are online at one time and the ISPs can "get away" with not having enough IP addresses for each user.
In order to use a dynamic IP address, a service such as Dynamic Host Configuration Protocol (DHCP) is used to assign addresses dynamically to devices as they request them. If a static address is used, it must be manually programmed into parameters of the device's network interface. (It is also possible to "fake" static IP address assignments through DHCP by assigning the same IP address to a computer — and no other — each time it is requested.)
