Have a look at the dhclient.conf man page. You probably want "also 
request" or "send".

"also request" asks the server to send back the named options in the 
response. For example domain-name-servers.

"send" is used to send an option to the server, such as the hostname.

The dhcp-options man page lists all the standard options. See the 
section "DEFINING NEW OPTIONS" for the syntax to define the options you 
are interested in. You need to specify the type so that dhclient can 
decode them appropriately (eg whether they are a text string, integer, 
IP address, etc. You need matching option definitions on the dhcp server.
