Dynamically Assigned Internet Addresses - RabbitCore RCM2000 Series Getting Started Manual

4.5 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 Intellicom 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 address 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 elsewhere on the Internet. If
you want to find out this dynamically assigned IP address, under Windows 98 you can run
the program while you are connected and look at the interface used to connect
winipcfg
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 RCM2200 from the Internet, you can place
the RCM2200 on the internal network using a private address assigned either statically or
through DHCP.
