univention-install univention-dhcp
DN1 () { sed -ne 's/^DN: //p;T;q';}
service="$(udm dhcp/service list|DN1)"
subnet="$(udm dhcp/subnet list --superordinate "$service"|DN1)"
net="$(udm dhcp/subnet list --superordinate "$service"|sed -ne 's/^  subnet: //;T;s/\.[0-9]*$//p;q')"
udm dhcp/subnet modify --dn "$subnet" --append range="$net.254 $net.2"

dhcpd doesn't complain, but the range is actually empty. UMC should detect this and warn <admin/handlers/dhcp/subnet.py#_ldap_modlist>.
BTW: high-address is optional.
