F.2.3 Dynamically Assigned Internet Addresses
In many instances, devices on a network do not have fixed IP addresses. This is the case when, for
example, you are assigned an IP address dynamically by your dial-up Internet service provider
(ISP) or when you have a device that provides your IP addresses using the Dynamic Host Config-
uration Protocol (DHCP). The MiniCore modules can use such IP addresses to send and receive
packets on the Internet, but you must take into account that this IP address may only be valid for
the duration of the call or for a period of time, and could be a private IP address that is not directly
accessible to others on the Internet. These addresses can be used to perform some Internet tasks
such as sending e-mail or browsing the Web, but it is more difficult to participate in conversations
that originate elsewhere on the Internet. If you want to find out this dynamically assigned IP
address, under Windows NT or later you can run the
command (
)
Start > Run >cmd
ipconfig
while you are connected and look at the interface used to connect to the Internet.
Many networks use IP addresses that are assigned using DHCP. When your computer comes up,
and periodically after that, it requests its networking information from a DHCP server. The DHCP
server may try to give you the same address each time, but a fixed IP address is usually not guar-
anteed.
If you are not concerned about accessing the MiniCore from the Internet, you can place the Mini-
Core on the internal network using an IP address assigned either statically or through DHCP.
