# Resolv

Resolv is a thread-aware DNS resolver library written in Ruby.  Resolv can

handle multiple DNS requests concurrently without blocking the entire Ruby

interpreter.

## Installation

Add this line to your application's Gemfile:

```ruby

gem 'resolv'

```

And then execute:

    $ bundle install

Or install it yourself as:

    $ gem install resolv

## Usage

```ruby

p Resolv.getaddress "www.ruby-lang.org"

p Resolv.getname "210.251.121.214"

Resolv::DNS.open do |dns|

  ress = dns.getresources "www.ruby-lang.org", Resolv::DNS::Resource::IN::A

  p ress.map(&:address)

  ress = dns.getresources "ruby-lang.org", Resolv::DNS::Resource::IN::MX

  p ress.map { |r| [r.exchange.to_s, r.preference] }

end

```

## Development

After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake test` to run the tests. 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](https://rubygems.org).
