NAME

Net::Domain::Registration::Check - Fast check on availability of domain registration

VERSION

Version 0.02

SYNOPSIS

This module takes a quick check on domain registration, to find out if the domain is available or not.

It doesn't query to whois server, but checks if domain exists on its parent nameservers.

So it gets a quick check.

For domain which is redemptionPeriod status, it does not get listed on parent nameservers, but you can't register it from the registrar this time. See: https://icann.org/epp#redemptionPeriod

It makes no sense on second-level ccTLDs, such as com.cn, co.uk etc. For IANA official root zone DB please see: https://www.iana.org/domains/root/db

该模块用来快速检查域名是否可以被注册。

它并不查询whois服务器，而是检查该域名是否存在于父一级的名字服务器上。

所以它的查询非常迅速，远快于whois.

某些待删除的域名处于redemptionPeriod状态，它确实不存在于父一级名字服务器上，但是这个时候你还不能注册。请见：https://icann.org/epp#redemptionPeriod

该模块并不能查询到ccTLD里，各国自己设置的二级域名，比如com.cn，co.uk。IANA官方定义的顶级域名gTLD和国家级域名ccTLD请见：https://www.iana.org/domains/root/db

Usage:

    use Net::Domain::Registration::Check;
	
    print domain_on_parent($domain) ? "domain has been taken" : "domain may not be taken";

Run via command line:

$ perl -MNet::Domain::Registration::Check -le 'print domain_on_parent(+shift)' yahoo.com
1

$ perl -MNet::Domain::Registration::Check -le 'print domain_on_parent(+shift)' yahoo.io
1

$ perl -MNet::Domain::Registration::Check -le 'print domain_on_parent(+shift)' yahoo.email
1

$ perl -MNet::Domain::Registration::Check -le 'print domain_on_parent(+shift)' yahoo234.com
0

$ perl -MNet::Domain::Registration::Check -le 'print domain_on_parent(+shift)' yahoo.nonexist
domain TLD not exists at -e line 1

EXPORT

This module exports only one method, domain_on_parent(), to check if domain exists on its parent nameservers.

该模块输出唯一的方法，domain_on_parent()，用来检查域名是否存在于父一级名字服务器上。

如果域名已存在于父一级名字服务器上，则肯定已经被注册了。反过来则可能未被注册。
