What is IP?

Asked by askeroo (10points) December 26th, 2007

I know it stands for Internet Protocol, but what is it? And how is it different from Transmission Control Protocol?

How do I find my IP address? And how do I change my IP address?

Well, I don’t know the exact definition either, but it goes something like that: computers communicate with one another and to identify themselves, they’re assigned an IP address. All websites we visit, have IPs, but instead of seeing and typing the IP in the location bar, we enter a domain, that is connected to the IP via DNS (domain name server).

Some IPs are dynamic (change in a period of time; let’s say 12 hours) and some are static.

To find your IP address, visit the You can change your IP only if it’s dynamic (you do this by reseting your modem).

Internet Protocol.

“The Internet Protocol (IP) is a data-oriented protocol used for communicating data across a packet-switched internetwork.

IP is a network layer protocol in the Internet protocol suite and is encapsulated in a data link layer protocol (e.g., Ethernet). As a lower layer protocol, IP provides the service of communicable unique global addressing amongst computers.”

to answer the other part of your question, i rely upon metaphor… if the internet were the postal system, then:

IP = the ZIP code system

TCP = the methods by which the post office sorts the mail so that it gets to the right address.
