NAME
       Mojo::IOLoop::Resolver - IOLoop DNS Stub Resolver

SYNOPSIS
	 use Mojo::IOLoop::Resolver;

	 # Lookup address
	 my $resolver = Mojo::IOLoop::Resolver->new;
	 $resolver->lookup('mojolicio.us' => sub {
	   my ($self, $address) = @_;
	   ...
	 });

	 # Resolve "MX" records
	 $resolver->resolve('mojolicio.us', 'MX', sub {
	   my ($self, $records) = @_;
	   ...
	 });

DESCRIPTION
       Mojo::IOLoop::Resolver is a minimalistic non-blocking I/O DNS stub
       resolver used by <Mojo:IOLoop>.	Note that this module is EXPERIMENTAL
       and might change without warning!

ATTRIBUTES
       Mojo::IOLoop::Resolver implements the following attributes.

   "ioloop"
	 my $ioloop = $resolver->ioloop;
	 $resolver  = $resolver->ioloop(Mojo::IOLoop->new);

       Loop object to use for I/O operations, defaults to a Mojo::IOLoop
       object.

   "timeout"
	 my $timeout = $resolver->timeout;
	 $resolver   = $resolver->timeout(5);

       Maximum time in seconds a "DNS" lookup can take, defaults to 3.

METHODS
       Mojo::IOLoop::Resolver inherits all methods from Mojo::Base and
       implements the following new ones.

   "is_ipv4"
	 my $is_ipv4 = $resolver->is_ipv4('127.0.0.1');

       Check if value is a valid "IPv4" address.

   "is_ipv6"
	 my $is_ipv6 = $resolver->is_ipv6('::1');

       Check if value is a valid "IPv6" address.

   "lookup"
	 $resolver->lookup('mojolicio.us' => sub {...});

       Lookup "IPv4" or "IPv6" address for domain.

	 $resolver->lookup('mojolicio.us' => sub {
	   my ($loop, $address) = @_;
	   print "Address: $address\n";
	   Mojo::IOLoop->stop;
	 });
	 Mojo::IOLoop->start;

   "resolve"
	 $resolver->resolve('mojolicio.us', 'A', sub {...});

       Resolve domain into "A", "AAAA", "CNAME", "MX", "NS", "PTR" or "TXT"
       records, "*" will query for all at once.	 Since this is a "stub
       resolver" it depends on a recursive name server for DNS resolution.

   "servers"
	 my @all     = $resolver->servers;
	 my $current = $resolver->servers;
	 $resolver->servers('8.8.8.8', '8.8.4.4');

       IP addresses of "DNS" servers used for lookups, defaults to the value
       of the "MOJO_DNS_SERVER" environment variable, auto detection, 8.8.8.8
       or 8.8.4.4.

DEBUGGING
       You can set the "MOJO_RESOLVER_DEBUG" environment variable to get some
       advanced diagnostics information printed to "STDERR".

	 MOJO_RESOLVER_DEBUG=1
