4.5 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 Internet service
provider (ISP) or when you have a device that provides your IP addresses using the
Dynamic Host Configuration Protocol (DHCP). The RCM3700 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
98 you can run the
program while you are connected and look at the interface
winipcfg
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 guaranteed.
If you are not concerned about accessing the TCP/IP Development Board from the
Internet, you can place the TCP/IP Development Board on the internal network using an
IP address assigned either statically or through DHCP.
