perl - 如何检查域名是否可用(批量)？

Question

我希望进行批量域名查找，看看是否有一些域名可供购买。我找不到 perl 模块，但似乎应该有一种方法可以在 perl 中执行此操作。我正在寻找免费的东西。谢谢!

这是一个需要 Net::DNS(相当常见的模块)的快速 Perl 脚本。

#!/usr/bin/perl

# Requirements
    use Net::DNS;

# Variables
    %VAR    =   (
                    db => './domains.txt',
                );

# Open file
    open (DB,$VAR{'db'});
    my (@domains) = <DB>;
    close (DB);

# Test domains
    foreach my $domain (@domains)
        {
            chomp($domain);

            my ($available) = &check_domain(domain => $domain);

            if ($available)
                {
                    print "$domain is available.<br />\n";
                }
            else
                {
                    print "$domain is NOT available<br />\n";
                }
        }

sub check_domain {

    # Test domain for existance

    # Variables
        my (%DATA) = @_ ;
        my ($available) = 0;

    # Start Net::DNS
        my $res = Net::DNS::Resolver->new;
        $res->udp_timeout(2);
        $res->tcp_timeout(2);

        my ($domain) = $res->search($DATA{'domain'});

        if ($domain)
            {
                ($available) = 1;
            }

    # Output
        return ($available);
}
