In your dhcpd.conf file, add in
ddns-domainname "your.domain.name";
ddns-update-style interim;
ddns-rev-domainname "in-addr.arpa";
ignore client-updates;
key "rndc-key" {
algorithm hmac-md5;
secret "your rndc secret key value goes here";
};
zone your.domain.name. {
primary 127.0.0.1;
key "rndc-key";
}
zone your.reverse.zone.inaddr.arpa. {
primary 127.0.0.1;
key "rndc-key";
}

Substituting, of course, for the proper values for your domain name,
your rndc secret key, your primary DNS server's IP address, and your
zone and reverse zone mapping names.

IIRC, you'll also have to set the update-policy values in your
named.conf zone definitions

Depends on the DHCP and DNS servers and the DNS clients as well.
If you use dnsmasq as the DHCP&DNS server, then it'll do
that automatically. I heard other DHCP servers can do that as well by
communicating with some other DNS server.

Of course, the clients need to provide the name they want to get
(unless you want to decide this centrally, which can be done as well,
obviously). With Debian clients, you just ned to edit the
/etc/dhclient.conf file and add "send host-name "<HOSTNAME>";".
