assert_zone

This small utility will help you verify that a DNS server is responding with the correct information, based on a zone file.

Add this line to your application's Gemfile:

gem 'assert_zone'

And then execute:

$ bundle

Or install it yourself as:

$ gem install assert_zone

It's simple: assert_zone ZONE_FILE [NAMESERVER] [options]

Assuming you have a zone file named zone.txt in the current directory, you can run assert_zone zone.txt to verify that each record in the zone file matches what the nameserver responds with.

By default, it will use the nameserver listed in the SOA record in the zone file. You can also specify a custom nameserver: assert_zone zone.txt ns1.example.com.

There are a few option flags you can add to the command:

• --color will display the results in color
• --use-local-resolver will not specify a nameserver and will use your system settings

After checking out the repo, run bin/setup to install dependencies. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
