This product is made up of several tools, available as a series of subcommands of dns-tools. The tools can be used to manage your DNS services in general but are particularly useful in data center and cloud migrations. Included are the following six tools; validator, impact, resolver, migrate, ptr and hosts. The tools are highly flexible and composable allowing you to easily automate your DNS needs.
