I wonder how we can find the IP address of those who visit our web sites. My site below has a free Bravenet Visitor counter on it.
An IP address (Internet Protocol address) is a unique address that certain electronic 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.
In other words, the IP address acts as a locator for one IP device to find another and interact with it. It is not intended, however, to act as an identifier that always
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 differs from other contact information, however, because the linkage of a user’s IP address to his/her name is not publicly available information.
Further, an IP address is not necessarily linked, in a persistent way, to a physical location or even data link layer address.
In the past, an IP address could be considered a unique identifier of a particular IP host, in addition to being a locator. When it was usable as an identifier, it was static, and it was assumed to be globally unique from end to end of the Internet.
In current practice, an IP address is less likely to be an identifier, due to technologies such as:
Dynamic assignment, as with an address that is assigned by the access device by which the user’s host connects over a dialup telephone line or by a set-top box for an IP over cable network
Network address translation, where the address visible on the Internet is the “outside” of a device that maps it to a completely different and hidden address on the “inside”
