The dhcpcd doesn't directly support dynamic DNS update, the dhcp server
may support it, at least the ISC dhcp version 3 does. You can do dynamic
DNS updates using the nsupdate command. See the man page for nsupdate for
details. Maybe you can do something with dhcpd.exe which is a script run
by the dhcp client.
Of course, the DNS server must be configured to allow dynamic updates.
