ii isc-dhcp-client 4.3.3-5ubuntu12.7
amd64 DHCP client for automatically obtaining an IP address
# netstat -anputa | grep -i dhclient
udp 0 0 0.0.0.0:68 0.0.0.0:*
150/dhclient
^^ expected result since Xenial does the opposite :
isc-dhcp-client : with random extra ports
isc-dhcp-client-ddns : with random extra ports
Basically, Xenial users has to install "isc-dhcp-client-ddns" if they
want the DDNS functionality.

Package has been removed :
rc isc-dhcp-client-noddns 4.2.4-7ubuntu12.10
amd64 Dynamic DNS (DDNS) disabled DHCP client
The upgrade does remove if installed "isc-dhcp-client-noddns" and
replaces it by "isc-dhcp-client".
