Asked on 4/9/2002, 8:21

I keep getting a popup ad that says "Internet Alert - you are being watched"
- or something like that. I know it is an ad but it told me my IP address
and said it is visible wherever I go.

Does that mean that no matter what email address I use, Ihave the same IP
address?

Where does the IP address come from and exactly what is it?

Can I stop it following me around?

Hi SuperFly2

IP Address (From Webopedia.com): "An identifier for a computer or device on a TCP/IP network. Networks using the TCP/IP protocol route messages based on the IP address of the destination. The format of an IP address is a 32-bit numeric address written as four numbers separated by periods. Each number can be zero to 255. For example, 1.160.10.240 could be an IP address.
Within an isolated network, you can assign IP addresses at random as long as each one is unique. However, connecting a private network to the Internet requires using registered IP addresses (called Internet addresses) to avoid duplicates.

The four numbers in an IP address are used in different ways to identify a particular network and a host on that network. Three regional Internet registries -- ARIN, RIPE NCC and APNIC -- assign Internet addresses from the following three classes.

Class A - supports 16 million hosts on each of 127 networks
Class B - supports 65,000 hosts on each of 16,000 networks
Class C - supports 254 hosts on each of 2 million networks
The number of unassigned Internet addresses is running out, so a new classless scheme called CIDR is gradually replacing the system based on classes A, B, and C and is tied to adoption of IPv6."

http://www.webopedia.com/TERM/I/IP_address.html

Well, let's say your IP address is like your ID, and it gotta be unique. It is given to you by your Internet service Provider, some IP address are static (You ISP will always assign you the same IP address), and some other will change everytime you connect to the net.

Can you hide it?, well, yes and no.

every time you go to a website, everytime you hit a link, you are sending your IP address to that website, and not only websites, it could be an IRC Network, or when you are dowloading that cool song you heard on radio.

There are ways to hide your IP from websites, for example, you can use a proxy server (from webopedia.com): "A server that sits between a client application, such as a Web browser, and a real server. It intercepts all requests to the real server to see if it can fulfill the requests itself. If not, it forwards the request to the real server. "

http://www.webopedia.com/TERM/p/proxy_server.html

So, this proxy server will hide your ip address from websites, as everytime you hit a link, it will receive the data and then it will forward it to you.

Some ISP offers proxy servers, ask your ISP, or go to www.google.com and type "proxy servers list"

If nothing of this helps please reply back including a copy of all previous emails
