Address Resolution using NetBIOS WINS
Windows Internet Naming Service (WINS) is a name resolution service that Microsoft DHCP clients use 
to correlate host names to IP addresses within a group of networks. Microsoft DHCP clients can be one of 
four types of NetBIOS nodes: broadcast, peer-to-peer, mixed, or hybrid.
Allocate Addresses to BOOTP Clients
Network segments may have both BOOTP and DHCP clients. In this kind of environment, there might be 
a BOOTP server and a DHCP server to serve the two types of clients separately. However, DHCP servers 
respond to a BOOTP requests, which in this case would be undesirable because BOOTP clients might 
receive an address from the DHCP pool. To prevent this, you can configure the DHCP server to ignore 
BOOTP request packets so that only the BOOTP server serves BOOTP clients. 
Create Manual Binding Entries
An address binding is a mapping between the IP address and Media Access Control (MAC) address of a 
client. The DHCP server assign the client an available IP address automatically, and then creates a entry in 
the binding table. However, the administrator can manually create an entry for a client; manual bindings 
are useful when you want to guarantee that particular network device receives a particular IP address. 
Manual bindings can be considered single-host address pools. There is no limit on the number of manual 
bindings, but you can only configure one manual binding per host.

Specify the NetBIOS Windows Internet Naming 
Service (WINS) name servers, in order of preference, 
that are available to Microsoft Dynamic Host 
Configuration Protocol (DHCP) clients.

2
Specify the NetBIOS node type for a Microsoft 
DHCP client. Dell Force10 recommends specifying 
clients as hybrid.

Enables address allocation to BOOTP clients. The 
addresses are from the DHCP address pool for the

Note: FTOS does not prevent you from using a network IP as a host IP; be sure to not use a network IP 
as a host IP.
