Manually distributing IP addresses, MacIP Serving

C-8 User’s Reference Guide

one hour after the last heard lease request as some other DHCP implementations may hold on to the lease for an additional time after the lease expired, to act as a buffer for variances in clocks between the client and server.

MacIP Serving

Macintosh Workstation (MacTCP or Open Transport):

Once the Mac workstation requests and receives a valid address, the Netopia R2121 will actively check for the workstation’s existence once every minute.

■For a DYNAMIC address, the Netopia R2121 will release the address back to the address pool after it has lost contact with the Mac workstation for over 2 minutes.

■For a STATIC address, the Netopia R2121 will release the address back to the address pool after it has lost contact with the Mac workstation for over 20 minutes.

Netopia R2121 MacIP Server Characteristics

The Mac workstation uses ATP to both request and receive an address from the Netopia R2121's MacIP server. Once acquired, NBP conﬁrm packets will be sent out every minute from the Netopia R2121 to the Mac workstation.

Manually distributing IP addresses

If you choose to manually distribute IP addresses, you must enter each computer’s address into its TCP/IP stack software. Once you manually issue an address to a computer, it possesses that address until you manually remove it. That’s why manually distributed addresses are sometimes called static addresses.

Static addresses are useful in cases when you want to make sure that a host on your network cannot have its address taken away by the address server. A network administrator’s computer, a computer dedicated to communicating with the Internet, and routers are appropriate candidates for a static address.

Using address serving

The Netopia R2121 provides three ways to serve IP addresses to computers on a network. The ﬁrst, Dynamic Host Conﬁguration Protocol (DHCP), is supported by PCs with Microsoft Windows and a TCP/IP stack. Macintosh computers using Open Transport and computers using the UNIX operating system may also be able to use DHCP. The second way, MacIP, is for Macintosh computers. The third way, called Serve Dynamic WAN Clients (IPCP), is used to fulﬁll WAN client requirements

The Netopia R2121 can use both DHCP and MacIP. Whether you use one or both will depend on your particular networking environment. If that environment includes both PCs and Macintosh computers that do not use Open Transport, you will need to use both DHCP and MacIP to distribute IP addresses to all of your computers.

Serve dynamic WAN clients

The third method, used to fulﬁll WAN client requirements, is called Serve Dynamic WAN Clients. This is a subset of PPP. Originally, this would apply only to switched WAN interface routers, and not to leased line routers. However, a new feature can give you Asynchronous PPP dial-in support on the Auxiliary port on any router including leased line Netopia routers.

R2121 specifications

The Netopia R2121 is a powerful and versatile router designed for both home and office environments, providing seamless connectivity and robust performance for various networking needs. This device offers a range of features and technologies that cater to the demands of modern users seeking reliable internet access, speed, and security.

One of the standout characteristics of the Netopia R2121 is its dual-band technology, which operates on both the 2.4 GHz and 5 GHz frequency bands.
