# DNS::Zonefile

The format of a DNS Zonefile is defined in RFC 1035 section 5 and RFC
1034 section 3.6.1. To anyone who's using BIND they'll look very
familiar.

This is an attempt to use Ruby parse them into an object graph which can
be investigated programatically, manipulated, validated or printed into
some canonical form.


## Getting setup

Add `gem dns-zonefile` to your Gemfile

or

`gem install dns-zonefile`

Okay, you're ready to move onto the examples now.

## Examples

Using raw data from the parser. Note that "@" isn't translated in this mode.
Nor are inherited TTLs interpreted.

```ruby
zonefile = "/path/to/file.zone"
zone_string = File.read(zonefile)
zone = DNS::Zonefile.parse(zone_string)

puts zone.soa.origin.to_s
puts zone.soa.ns.to_s
puts zone.rr[0].to_s
```

Using more structure data. @, TTLs, and empty hostname inheritance are all
handled in this mode.

```ruby
zonefile = "/path/to/file.zone"
zone_string = File.read(zonefile)
zone = DNS::Zonefile.load(zone_string)
# or, if no $origin is in the zone file
zone = DNS::Zonefile.load(zone_string, 'example.com.')

puts zone.soa.origin
puts zone.soa.nameserver
puts zone.records[1]
# get all MX records
puts zone.records_of(DNS::Zonefile::MX)
```

Open the examples in the `./examples` directory to see more examples.
