Question

i want to know about tthe IP adress of a computer.

Answer 1

An IP address (Internet Protocol address) is a unique address that devices use in order to identify and communicate with each other on a computer network utilizing the Internet Protocol standard (IP)—in simpler terms, a computer address. Any participating network device—including routers, computers, time-servers, printers, Internet fax machines, and some telephones—can have their own unique address. Also, many people can find personal information through IP addresses.

An IP address can also be thought of as the equivalent of a street address or a phone number (compare: VoIP (voice over (the) internet protocol)) for a computer or other network device on the Internet. Just as each street address and phone number uniquely identifies a building or telephone, an IP address can uniquely identify a specific computer or other network device on a network.

An IP address can appear to be shared by multiple client devices either because they are part of a shared hosting web server environment or because a proxy server (e.g., an ISP or anonymizer service) acts as an intermediary agent on behalf of its customers, in which case the real originating IP addresses might be hidden from the server receiving a request. The analogy to telephone systems would be the use of predial numbers (proxy) and extensions (shared).

IP addresses are managed and created by the Internet Assigned Numbers Authority. IANA generally allocates super-blocks to Regional Internet Registries, who in turn allocate smaller blocks to Internet service providers and enterprises.

IP header size is 20 bytes.

Answer 2

Well this depends on lot of factors. You have 2 computers. DO u use a dial up connection? If yes then the IP changes with every session this is because you get a dynamic IP address that changes. If you have a high speed connection then you might have a static IP address, that purely depends on the service provider. To have a check on the IP address follow this step. For windows systems. Start> run> type"command"> then type "ipconfig" It will show your IP address, you can check it every time after every session does your IP change or not. Hope this answers your question.

Answer 3

An IP address is the means that allows information to be sent to your computer. It usually looks something like this: (IPv4)10.123.15.254 with each dotted number ranging from 0 to 255 for a total of 4,294,967,296 unique addresses. Unfortunately , we're running out and a new type called IPv6 is being released with will allow for 2^128 addresses; this is approximately 5×10^28 addresses for each of the roughly 6.5 billion people alive today.

This address is what allows you to communicate over the internet. I've included info regarding IPv6 and internet addressing from Wikipedia.

Answer 4

All those numbers and stuff at the top of some emails. An IP address is the unique address for you computer. The unique code leads back to your Internet provider and from there to your computer. The IP address is how they are able to track and catch criminals that use their computers to perpetrate their crimes.
