DHCP Server options
A FastIron configured as a DHCP server can support up to 1000 DHCP clients, offering them the
following options:
• NetBIOS over TCP/IP Name Server - Specifies a list of RFC1001/1002 NBNS name servers
listed in order of preference.
• Domain Name Server - Specifies a list of Domain Name System (RFC 1035) name servers
available to the client. Servers are listed in order of preference.
• Domain Name - Specifies the domain name the client should use when resolving hostnames
using the Domain Name system.
• Router Option - specifies a list of IP addresses for routers on the client subnet. Routers are
listed in order of preference.
• Subnet Mask - Specifies the client subnet mask (per RFC950).
• Vendor Specific Information - Allows clients and servers to exchange vendor-specific
information.
• Boot File - Specifies a boot image to be used by the client
• Next Bootstrap Server - Configures the IP address of the next server to be used for startup by
the client.
• TFTP Server - Configures the address or name of the TFTP server available to the client.
A DHCP server assigns and manages IPv4 addresses from multiple address pools, using dynamic
address allocation. The DHCP server also contains the relay agent to forward DHCP broadcast
messages to network segments that do not support these types of messages.
