Netopia r6100 Verweisanleitung

To set up a connection to the Internet, you may have obtained a block of IP host addresses from an ISP. When 
configuring the Netopia R6000 Series, you gave one of those addresses to its Ethernet por t, leaving a number 
of addresses to distribute to computers on your network.

There are two schemes for distributing the remaining IP addresses: 

■

Manually give each computer an address 

■

Let the Netopia R6000 Series automatically distribute the addresses

These two methods are not mutually exclusive; you can manually issue some of the addresses while the rest 
are distributed by the Netopia R6000 Series. Using the router in this way allows it to function as an address 
ser ver.

One reason to use the Netopia R6000 Series as an address ser ver is that it takes less time than manually 
distributing the addresses. This is par ticularly true if you have many addresses to distribute. You need to enter 
information only once, rather than having to enter it on each host separately. This also reduces the potential for 
misconfiguring hosts.

Another reason to use the Netopia R6000 Series as an address ser ver is that it will distribute addresses only 
to hosts that need to use them.

All Netopia R6000 Series Routers come with an integrated Dynamic Host Control Protocol (DHCP) ser ver. Some 
routers also come with a Macintosh Internet Protocol (MacIP) ser ver. These ser vers provide a means of 
distributing IP addresses to either a Mac or PC workstation as needed.

When setting up the DHCP or MacIP ser vers in the Netopia R6000 Series, it is necessar y to understand how 
workstations lease, renew, and release their IP addresses. This information is helpful in determining dynamic 
address allocation for a network.

The term “lease” describes the action of a workstation requesting and using an IP address. The address is 
dynamic and can be returned to the address pool at a later time.

The term “renew” refers to what the workstations do to keep their leased IP address. At cer tain inter vals, the 
workstation talks to the DHCP or MacIP ser ver and renews the lease on that IP address. This renewal allows 
the workstation to keep and use the assigned IP address until the next renewal period.

The term “release” refers to a situation where the workstation is no longer using its assigned IP address or has 
been shut down. IP addresses can be manually released as well. The IP address goes back into the DHCP or 
MacIP address pool to be reassigned to another workstation as needed.
