Re: Which servers support secondary network numbers?

[Tim Peiffer <[e-mail]>]

The Internet Software Consortium is developing a dhcp
server as a reference standard.  It can handle manual
assignments and dynamic assigned addresses from pools on 
any of the networks (physical or logical) assigned to 
the interface..

I have seen references to the server the wobus faq,
but the FAQ is woefully out of date.  Ted Lemon is doing
good work on this package.

excerpts from dhcpd.conf:

shared-network FUGUE

# option definitions common to this shared network.
  option subnet-mask 255.255.255.224
  default-lease-time 600 max-lease-time 7200

# One of the two IP subnets that share this physical network
#
# Address ranges can be specified for each subnet attached to
# a shared network.   Since these subnets share the same physical
# network, addresses are pooled together, and assignments are made
# without regard to the actual subnet.   If the optional dynamic-bootp
# keyword is given in the address range declaration, then addresses
# in that range can be assigned either with the DHCP protocol or the
# BOOTP protocol; otherwise, only DHCP clients will have addresses
# allocated from the address range.
#
# Note that each IP subnet can have its own options specific to that subnet.
# options that aren't specified in the subnet are taken from the shared
# network (if any) and then from the global option list.
