Is this a Linux/Unix like system ? I know on GNU/Linux systems, the ISC client
is typically called by a script, and also calls a script to configure the OS
when it gets a lease or the lease expires.
Depending on how dynamic the information needs to be, then you can configure
the client to add customer options - and if you configure the scripts
correctly, to do something with options returned. You may have issues changing
the information - you may have to detect the change, and restart the client for
it to take effect.

Perhaps I was not clear in my original question.
Yes, this is a linux system. I know that there is a script
(dhclient-script) that is run when the lease is aquired but I want to send
things to the dhcp server in the request. And the thing I want to send is
read (in ways not related to the question) from the system during boot.

man dhclient includes documentation for:
-I <dhcp-client-identifier>
Specify the dhcp-client-identifier option to send to the
DHCP server.
-H <host-name>
Specify the host-name option to send to the DHCP server.
-V <vendor-class-identifier>
Specify the vendor-class-identifier option to send to the
DHCP server.
-R <option>[,<option>...]
Specify the list of options the client is to request from
the server.
The default option list is:
subnet-mask, broadcast-address, time-offset, routers,
domain-search, domain-name, domain-name-servers,
host-name,
nis-domain, nis-servers, ntp-servers, interface-mtu

Thanks, those would be great and in principal this is what I need.
However, what I am looking for is to set the option 125 ("vivso") in this
way. (I am aware that vivso is also something that can be requested from
the dhcp server, but I am working with the part that sends vivso *from* the
client *to* the server, as required in the TR111 spec.)

Subject: Problem with shared-network
Message-ID:
<[email protected]>
Content-Type: text/plain;charset=iso-8859-1
I have a Debian 7.0 running isc-dhcp-server 4.2.2.
My server has a single NIC, and using iproute, I've added additional
addresses (some lines snipped for brevity):
eth0 Link encap:Ethernet HWaddr 00:50:56:XX:XX:XX
inet addr:192.168.220.111 Bcast:192.168.220.255
Mask:255.255.255.0
eth0:1 Link encap:Ethernet HWaddr 00:50:56:XX:XX:XX
inet addr:10.111.111.1 Bcast:10.255.255.255 Mask:255.255.255.0
My goal is for the dhcp server to hand out unknown clients addresses from
the 10.111.111.X pool, and known client to get something from the
192.168.220.X pool. Since these are on the same subnet, I [believe] this
requires a shared-network block. My dhcpd.conf file looks like (with
comments and global options stripped out for brevity):
shared-network my-net {
subnet 192.168.200.0 netmask 255.255.255.0 {
range 192.168.200.194 192.168.200.200;
range 192.168.200.215 192.168.200.250;
ignore unknown-clients;
<bunch of options removed>
} #subnet 192.168.200.0
subnet 10.111.111.0 netmask 255.255.255.0 {
range 10.111.111.5 10.111.111.200;
allow unknown-clients;
<bunch of options removed>
} #subnet 10.111.111.0
} #shared-network
It runs, but only gives out 192 addresses. If I reverse the order, so the
10 subnet declaration comes first, then it hands out 10 addresses, but not
192 addresses.
Any ideas what I am doing wrong?
