You don't need to provide any physical address or data about your computer to have and internet connection.
The Computer Numeric address or configuration ID should not be asked.
The internet provider may have asked so that you cannot use the internet on any other system and it will need configuration to connect from other PC.
Your IP (internet provider) address.
a computer address (ip) is provided by your internet provider and can sometimes be made by the user.
it is the work of the Internet service provider to locate and assign the ip address, when ever any client computer is connected to the Internet.
Your IP address does not depend on your computer but upon your internet service provider. It dynamically changes on a regular basis. If you change your ISP, then your IP address would definitely change.
Your email is stored by your email or internet provider. If you can get a connection, by any computer, to the Internet, you can simply log on to your account. At work, connect to the Internet. Type in the address of your email provider, log on with your name and password and go to your email. You will be able to pick up unread emails and send new ones. Depending on the policies of your provider, some emails are stored for a period.
Your internet provider has nothing to do with your email address. Your internet provider simply gives you internet access. You email address is through a search engine company ( google, yahoo, aol, msn and so on). If you was to swap say from a cable internet provider to a dsl provider you will be able to keep your current email address.
Yes, it is possible to change your internet service provider address but it is usually necessary to change your email address or obtain a secondary email. This is much less complicated than removing current ISP from your computer which involves deleting and uninstalling current ISP software.
There is no physical address.
Email goes from your computer to another computer that a service provider has; for example, if the email address is going to someone@gmail.com, then google has a computer (or a bank of computers) that receives your email. Then the intended recipient of your email can obtain it from google's computer. Google stores it for him or her, until he or she looks for it. The physical location of all these computers does not alter the way it works. All computers can connect to each other through the internet.
IP means Internet Protocol Address. It is a address used by a computer or laptop when connecting to internet. It is assigned by the Internet Service Provider or automatically assigned. Using of IP addresses usually prevents cyber theft and malpractices.
IP address trackers work by locating the IP address of a user. From this IP address, geographical information can be gathered about the user such as the specs of the computer, the location, the Internet Service Provider, etc.
If your address book vanished, try rebooting your computer. It might not be gone. It just may have disappeared for some reason or the other. A reboot might clear up the problem. If that does not work, frequently, your service provider will have a copy. When you reboot and then get back on the internet you will find your service provider or e-mail provider reinstalls your address book. If that does not happen, many computers have automatic backups. You can go back to a time before your computer address book vanished. Then you can turn your computer back to the time before you lost your address book.
