Relying on clients hosting resources for other clients is
far from optimal. Any resources in your network needed 
by other clients _should_ be stored and kept by "servers".

Givin the users habits to cross-reference resources is 
teh same as giving them bad habits.

Said that, the next question "howto update dns from dhcpd" is
best answered by reading the dhcpd documentation.

Man dhcpd.conf ( mine is a little old:Internet Software Consortium 
DHCP Server V3.0.1rc4), read about "ddns-*" configuration 
statements.

There is an older thread on this subject where Cricket Liu

subject, i'll quite a few lines:

Try adding:

zone rols.org. {
    primary <address of primary master name server>;
}

zone 45.168.192.in-addr.arpa. {
    primary <address of primary master name server>;
}

to dhcpd.conf.
