Description: dhcp-dns-tools management of computer names and IP addresses
 DDT is an acronym for DHCP-DNS-Tools.
 In practise, DDT is an IP Address Management (IPAM) service.
 It has been used in the LEGI laboratory for over 10 years.
 ddt (dhcp-dns-tools) is a small tool to maintain a set of computers/IP.
 In order to help you in this task, ddt command has a set of action
 to generated DHCP and DNS configuration files.
 .
 The tool is quite effective and tries to keep things simple
 but easily configurable for your site like a swiss army knife.
 Everything is saved in a YAML database
 and entries could be added, deleted, or modified by the command line.
