威瑞信是否即将更改过期的域掉落捕获游戏？
专利申请表明，威瑞信可能正在撼动当前的系统。
这就是过期域名下降捕获系统在当今.com的工作方式。丢弃捕获器在丢弃的那一秒就以域名为目标，并尝试在其数百个拥有和运营的注册商以及合作伙伴之间进行协调，以注册尽可能多的理想域名。
但是.com注册管理机构威瑞信是否准备改变其工作方式？
专门为抓取丢弃域名而创建的新注册商数量的爆炸式增长至少部分是由威瑞信的一些速率限制措施引起的。现在有迹象表明它将做出进一步的改变。
首先，ICANN预测，这些注册服务商中的一些将在明年关闭。
然后是：威瑞信制定了一项详细的计划，以确定哪些注册商正在共同努力进行掉落捕获并“减轻”他们的努力。
美国专利商标局今天公布了威瑞信的专利申请，内容是“检测和缓解域名添加收购中的注册商串通”。该申请于2015年12月31日提交。
它描述了确定哪些注册商正在代表客户共同获取域名的方法。虽然大多数专利申请都讨论了如何找出这种共谋，但也讨论了如何减轻它：
缓解操作的示例包括记录一对 DNS 注册商之间潜在的删除-添加串通，通知注册管理机构或其用户一对 DNS 注册商之间潜在的删除-添加串通，向注册管理机构发送请求以限制或阻止来自一对或两个 DNS 注册商的当前和/或未来的域名获取请求， 等等。
当前的下降捕获系统是否对威瑞信的资源负担过重？还是有别的事情发生？
Is Verisign about to change the expired domain drop catching game?
Patent application shows that Verisign might be shaking up the current system.
Lots of well-timed firepower.
That’s how the expired domain name drop catching system works in .com today. Drop catchers target domain names the second they drop, and try to coordinate amongst their hundreds of owned-and-operated registrars as well as partners to register as many of the desirable domain names as possible.
But is .com registry Verisign getting ready to change how this works?
The explosion in the number of new registrars created solely for grabbing dropping domains was precipitated, at least in part, by some rate limiting actions by Verisign. Now there are signs that it will make further changes.
First, ICANN predicts that a number of these registrars will be shut down over the next year.
Then there’s this: a detailed plan by Verisign for how to determine which registrars are working together for drop catching and to “mitigate” their efforts.
The U.S. Patent and Trademark Office published a patent application from Verisign today for “Detecting and Mitigating Registrar Collusion in Drop-Add Acquisitions of Domain Names” (pdf). The application was filed on December 31, 2015.
It describes ways to figure out which registrars are working together to grab domains on behalf of clients. While most of the patent application discusses how to figure out this collusion, there’s also talk of how to mitigate it:
Examples of mitigating actions include logging the potential drop-add collusion between the pair of DNS registrars, notifying the registry or a user thereof of the potential drop-add collusion between the pair of DNS registrars, sending a request to the registry to throttle or block current and/or future domain name acquisition requests from one or both of the pair of DNS registrars, and the like.
Does the current drop-catching system tax Verisign’s resources too much? Or is there something else going on?
