Concept Guide

Congure a Method of Hostname Resolution

Dell systems are capable of providing DHCP clients with parameters for two methods of hostname resolution—using DNS or NetBIOS

WINS.

Using DNS for Address Resolution

A domain is a group of networks. DHCP clients query DNS IP servers when they need to correlate host names to IP addresses.

1 Create a domain.

DHCP <POOL>

domain-name name

2 Specify in order of preference the DNS servers that are available to a DHCP client.

DHCP <POOL>

dns-server address

Using NetBIOS WINS for Address Resolution

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.

1 Specify the NetBIOS WINS name servers, in order of preference, that are available to Microsoft Dynamic Host Conguration Protocol

(DHCP) clients.

DHCP <POOL> mode

netbios-name-server address

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

DHCP <POOL> mode

netbios-node-type type

Creating Manual Binding Entries

An address binding is a mapping between the IP address and the media access control (MAC) address of a client.

The DHCP server assigns the client an available IP address automatically, and then creates an 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 a 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 congure one manual binding per host.

NOTE

: Dell EMC Networking OS 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.
