User’s Manual 596.2.3 Dynamically Assigned Internet AddressesIn many instances, devices on a network do not have fixed IP addresses. This is the casewhen, for example, you are assigned an IP address dynamically by your dial-up Internetservice provider (ISP) or when you have a device that provides your IP addresses usingthe Dynamic Host Configuration Protocol (DHCP). The RCM3365/RCM3375 modulescan use such IP addresses to send and receive packets on the Internet, but you must takeinto account that this IP address may only be valid for the duration of the call or for aperiod of time, and could be a private IP address that is not directly accessible to others onthe Internet. These addresses can be used to perform some Internet tasks such as sendinge-mail or browsing the Web, but it is more difficult to participate in conversations thatoriginate elsewhere on the Internet. If you want to find out this dynamically assigned IPaddress, under Windows 98 you can run the winipcfg program while you are connectedand look at the interface used to connect to the Internet.Many networks use IP addresses that are assigned using DHCP. When your computercomes up, and periodically after that, it requests its networking information from a DHCPserver. The DHCP server may try to give you the same address each time, but a fixed IPaddress is usually not guaranteed.If you are not concerned about accessing the RCM3365/RCM3375 from the Internet, youcan place the RCM3365/RCM3375 on the internal network using an IP address assignedeither statically or through DHCP.
