I hapened across OpenNIC (http://www.opennic.unrated.net) this morning as I was searching for some public name servers to test against. I had made a DNS change 72 hours ago and some broadband ISP’s were still not picking up the change.
今天早晨，当我在寻找一些要测试的公共名称服务器时，我在OpenNIC ( http://www.opennic.unrated.net )上跳来跳去 。 我在72小时前进行了DNS更改，一些宽带ISP仍未进行更改。
OpenNIC is more than just public DNS — however — for the purposes of my testing, it worked great to confirm that it was in fact the ISP’s and not some errant BIND mistake.
OpenNIC不仅仅是公共DNS，但是-就我的测试而言，它非常有用，可以确认它实际上是ISP的错误，而不是一些错误的BIND错误。
After resolving my issues, I looked a bit further into the site and was pleasantly surprised to find a unique public DNS system in place. Not only could one use these name servers at the server, system or personal computer level, but could also experiment with free alternative Top Level Domains (TLDs) for personal use, i.e. .indy, .geek, .null, .oss and .parody. Now of course these domains are only visible to those using OpenNIC DNS, however, that is what was so interesting to me. One could put a domain on a public server and it is by default restricted to those in the community, great for development and staging, or just for hobbyist efforts.
解决问题后，我进一步浏览了该站点，并为找到合适的独特公共DNS系统感到惊讶。 人们不仅可以在服务器，系统或个人计算机级别使用这些名称服务器，而且还可以尝试免费使用供个人使用的备用顶级域(TLD)，即.indy，.geek，.null，.oss和.parody。 。 当然，现在这些域仅对那些使用OpenNIC DNS的用户可见，但是，这对我来说很有趣。 可以将域放在公共服务器上，默认情况下，该域仅限于社区中的用户使用，非常适合开发和登台，或者仅用于业余爱好者。
Secondarily, since OpenNIC supports all the major TLDs (.com, .net, .org, .mil, .gov, .edu and so on including two character country codes), one benefits by also having access to name resolution for the remainder of the Internet. OpenNIC also supports AlterNIC and Pacific Root domains.
其次，由于OpenNIC支持所有主要的TLD(.com，.net，.org，.mil，.gov，.edu等，包括两个字符的国家/地区代码)，因此，在其余的TLD中也可以使用名称解析，这是一个好处。互联网。 OpenNIC还支持AlterNIC和Pacific Root域。
Definitely worth a browse to see how some communities on the Internet remain independent and centralized around users.
绝对值得一看，以了解Internet上的某些社区如何保持独立并围绕用户集中。
