关于“Comodo Secure DNS”的疑问？

[wwwww]

该网站 http://www.Comodo.com/secure-dns/ 给出的 Comodo Secure DNS 的 IP地址为: 156.154.70.22 , 156.154.71.22

但安装 cispremium_installer_x86.exe 却提示是否使用 Comodo Secure DNS 的 IP地址为: 156.154.70.25 , 156.154.71.25

有谁清楚是怎么回事吗？盼答复，先谢谢了！尽管目前我一直在使用的是 Google Public DNS 。

还是按网站上的IP地址好些，不过156.154.70.25 , 156.154.71.25也都应该是属于Comodo的DNS服务器的地址，网站上的介绍里面有：Comodo Secure DNS's server infrastructure currently spans 15 locations (nodes) and five continents around the world.

谢谢 TinkerBell !

可能我有些较真，但疑问依旧：
More Reliable - Comodo Secure DNS's server infrastructure currently spans 15 locations (nodes) and five continents around the world. This allows Comodo to offer you the most reliable fully redundant DNS service anywhere. Each node has multiple servers and is connected by several Tier 1 carriers to the Internet.

查询Whois数据库可以看到156.154.0.0 - 156.154.255.255这个网段都是属于NeuStar, Inc所有的，这个公司是Biz域名的管理机构，Comodo 可能也是在使用NeuStar, Inc的DNS Service。
