6.5 Dynamically Assigned Internet Addresses
In many instances, there are no 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 Configu-
ration Protocol (DHCP). The RCM2100 RabbitCore 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 private
addresses can be used to perform some Internet tasks such as sending e-mail or browsing
the Web, but usually cannot be used to participate in conversations that originate else-
where on the Internet. If you want to find out what this dynamically assigned IP address is,
under Windows XP you can run the ipconfig program while you are connected and look
at the interface used to connect to the Internet.
Many networks use private IP addresses that are assigned using DHCP. When your com-
puter 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 guaranteed.
If you are not concerned about accessing the RCM2100 from the Internet, you can place
the RCM2100 on the internal network using a private address assigned either statically or
through DHCP.
