What is IP Address?

Question

What is IP Address?

Answer 1

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.



Because the numbers may be tedious to deal with, an IP address may also be assigned to a Host name, which is sometimes easier to remember. Hostnames may be looked up to find IP addresses, and vice-versa. At one time ISPs issued one IP address to each user. These are called static IP addresses. Because there is a limited number of IP addresses and with increased usage of the internet ISPs now issue IP addresses in a dynamic fashion out of a pool of IP addresses (Using DHCP). These are referred to as dynamic IP addresses. This also limits the ability of the user to host websites, mail servers, ftp servers, etc. In addition to users connecting to the internet, with virtual hosting, a single machine can act like multiple machines (with multiple domain names and IP addresses).



Knowing your IP address can allow you (and others you tell) to access services running on your machine such as online games, servers (FTP, web, mail), and remote access utilities (PCAnywhere, GoToMyPC, MS Remote Desktop).

Answer 2

Ip Address (Internet Protocol address) is as your telephone number. It uniquely identifies every host on a network. Just as your mailing address uniquely identifies your home, an IP address uniquely identifies a host.

Subnetting is the process of dividing a block of IP addresses assigned as a Class A, B, or C network into multiple smaller blocks of addresses. This hour addresses the needs and benefits of subnetting, as well as the steps and procedures you should follow to generate a subnet mask.

Answer 3

Here I give simple answer to this...

I think u came across this question while checking property of LAN.



1) IP Address:- It is adress given to computer while ur pc is connected to Network(LAN or internet). Simply i can say As it is like phone number to ur mobile phone, ip addtess for ur computer.



2) Subnet Mask:- It's related to IP adress.



3) Gateway:- Its is a computer which help to establish communication between PC's of different OS environment(e.g. Windows and Linux)



4) DNS (Domani Naming server) : I would like to explain by giving example. E.g. In telephone directory u have Name and his phone number same like that DNS means its a computer which has website name and its IP address so that u can directly enter website address in browser instead of IP address which is difficult to remember.

Answer 4

Every machine on the Internet has a unique identifying number, called an IP Address. A typical IP address looks like this:



* 216.27.61.137



subnet mask: A number that is used to identify a subnetwork so that IP addresses can be shared on a local area network. It look like



* 255.255.255.0



The gateway in a network that a computer will use to access another network. Simly for you , it is used to direct Internet traffic from the local network to the cable or DSL modem, which connects to the Internet service provider.



DNS (Domain Name System) A system for converting host names and domain names into IP addresses on the Internet or on local networks that use the TCP/IP protocol. For example, when a Web site address is given to the DNS either by typing a URL in a browser or behind the scenes from one application to another, DNS servers return the IP address of the server associated with that name.

Answer 5

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.

Subnetwork



In computer networks which use the Internet Protocol, a subnetwork or subnet is a range of logical addresses within the address space that is assigned to an organization. Subnetting is a hierarchical partitioning of the network address space of an organization (and of the network nodes of an autonomous system) into several subnets. Routers constitute borders between subnets. Communication to and from a subnet is mediated by one specific port of one specific router, at least momentarily.

DNS

The Domain Name system (DNS) associates various sorts of information with so-called domain names; most importantly, it serves as the "phone book" for the Internet by translating human-readable computer hostnames, e.g. en.wikipedia.org, into the IP addresses, e.g. 66.230.200.100, that networking equipment needs to deliver information. It also stores other information such as the list of mail exchange servers that accept email for a given domain. In providing a worldwide keyword-based redirection service, the Domain Name System is an essential component of contemporary Internet use.

Search the web.

Answer 7

IP address is like a username for your computer on the internet. Without a IP Address you can't go onto the internet. Like some forums they have blocked all access unless you are a member/user.

For DNS IP:_192.168.1.5 Default Gateway :255.255.192.168

Answer 11

an ip address is the numbered code in which your computer is recognised on a network. for more help try contacting a windows help desk or you help and support centre which should be on your start menu.



hope this wasn't to detailed.

Answer 12

personal computer no.its the number which identifies ur computer's identity
