why is an ip address needed?

For the same reason that a house needs an address for mail to get there, it has to have a number to know where to go.

You can't an email address is not tied to an IP address.  Anyone could login and use email whether it's web based or not.

thru your ip address.

A public IP address can be used to address a computer from outside a network; a private IP address is used to address a computer from within a network.\n\nFor example, if you use a router for your home network, it tends to have the address 192.168.0.1 or the like. The first two numbers -- 192.168 -- indicate this is a private address; only computers on the network, behind the router, can reach IP addresses in that group.\n\nA public IP address might be 70.232.43.168; if you type that into your Web browser ( http://70.232.43.168 ), and there is a Web server operating on that IP address listening on a default HTTP port, you'll see the Web site.

If you're going to configure you own IP address and subnet mask, you might want to do a search and download a Free Subnet Calculator.  I have one and don't use it, it's best to use DHCP to get your IP address

I think your misunderstanding.  A dynamic ip address is not what you want, it changes everytime you log on.  and its not your address you need to worry about, its the address of wherever your connecting to.  I am not familier with the site no-ip.com, but if it wants you to mess with ip adresses I would be a little suspicious.

In most cases, the IP address is assigned by the network that the PC is connected to.  It is stored in the PC (if you're running Windows, RUN... the command line program called ipconfig to see what your IP address is).   The reason it doesn't often change is that when and if it is reassigned, the network will often assign the same address as before.\n\n(There is another address, called the MAC address, which is assigned at the factory and is permanently unique.   There's not normally any reason to be concerned with it.  It is used at a low level in the communication protocols.)

IP addresses are assigned\nYou can't change them\nIf u r on a network that has a server within (DHCP server) ask the network administrator if he can do that \n\nOtherwise if u r not in a network u have static IP address if u r using a 24 hour connection like DSL\nif u r using Dial-up then everytime u connect u will get a new IP address\n\nhaving a static IP address is not safe too\nif someone gets ur ip he can try hacking ur computer everytime u r online\notherwise using dial-up or assigning another IP if he gets it he can only use it for this connection session only because the next time u r connected u have another IP

you should simply be able to type in the ip in the address line.

DHCP dynamically assigns an IP address to your computer when it's connected to the network, so you don't have to specify an static IP address as configuration.

if you have no public IP adresses you can make connectin between computer with VPN and u need VPN server

No.  That's considered a directly connected device and it doesn't need or get an ip address.  In fact, the USB cable connected to the printer has no means of communicating on a standard ethernet network.

As already mentioned every computer uses an IP address and you can find out approximately where that computer is located (the name of the town or county or metropolitan area) easily. Past that you do have to goto the service provider, BUT its not a simply ask kinda thing unless you are law enforcement with a warrant. so if you're worried about some jerk telling you he knows where you are because of your IP address.. its very doubtful.

An IP address has 4 parts XXX.XXX.XXX.XXX each part is a numeric value in the range of from 0 to 255. The first two pairs are usually referred to as the network portion and identify the network. The second two pairs are usually refferred to as the host portion and identify the individual computer within the specified network. The IP address is used in conjunction with a Subnet Mask. This tells us specifically which bits are being used for the network id and which bits are being used for the host id.\n\nThere is no area code mapping! An individual IP address could be anywhere in the world.\n\nThis is only a very brief introduction, if you want more information, take a TCP/IP course at your local college or technical school.

yes, or set up a router to automatically assign ip addresses as the computers connect. good luck.

Internet Protocol address) The address of a device attached to an IP network (TCP/IP network). Every client, server and network device must have a unique IP address for each network connection (network interface). Every IP packet contains a source IP address and a destination IP address.\n\nStatic and Dynamic IP\n\nAn IP network is somewhat similar to the telephone network in that you have to have the phone number to reach a destination. The big difference is that IP addresses are often temporary.\n\nEach device in an IP network is either assigned a permanent address (static IP) by the network administrator or is assigned a temporary address (dynamic IP) via DHCP software. Routers, firewalls and proxy servers use static addresses as do most servers and printers that serve multiple users. Client machines may use static or dynamic IP addresses. The IP address assigned to your service by your cable or DSL Internet provider is typically dynamic IP. In routers and operating systems, the default configuration for clients is dynamic IP (see DHCP).\n\nDotted Decimals\n\nIP addresses are written in "dotted decimal" notation, which is four sets of numbers separated by periods; for example, 204.171.64.2. If you knew the IP address of a Web site, you could enter the dotted decimal number into your browser instead of the domain name (which is why we have DNS!).\n\nAlthough the next version of the IP protocol offers a virtually unlimited number of unique addresses (see IPv6), the traditional IP address (IPv4) uses a 32-bit number that defines both the network and the host computer. The network class determines how many of the 32 bits are used for the network address, leaving the remaining bits for use as the host number (note the numbers of networks and hosts in the table below). The host number can be further divided between subnetworks and hosts

The DHCP server at your ISP generates the IP address.  You are typing the correct commands to release/renew your IP address.  The IP address they issue is within a range of addresses on the network they have registered to be able to use.  You'll have to switch ISP's if you want to be on another network.
