这种情况，是不是运行商劫持了其他 DNS 服务器？

给家里路由器设置DNS服务器的时候，PING了一下发现，8.8.8.8延迟有200多毫秒，但是8.8.4.4只有不到2毫秒！于是就traceroute一下，结果是这样的：
root@TL-WR1043ND:~# traceroute 8.8.4.4
traceroute to 8.8.4.4 (8.8.4.4), 30 hops max, 38 byte packets

6 google-public-dns-b.google.com (8.8.4.4) 1.976 ms 2.344 ms 2.823 ms

直接从天津联通的服务器跳到Google去了...
至于8.8.8.8的结果还比较正常：

我又试了几个，114DNS也是延时1毫秒左右，而且几下就从天津联通直接跳到114DNS服务器：
traceroute to 114.114.114.114 (114.114.114.114), 30 hops max, 38 byte packets

6 public1.114dns.com (114.114.114.114) 1.951 ms 2.866 ms *

V2EX DNS 似乎没有问题。
我想请教，这是某种加速的技术，还是就是被运营商无耻劫持了其他DNS？解决方法除了VPN和代理之外，是不是就没有简单的办法了呢？我现在只好把114、Google两个DNS和V2EX DNS都加到ChinaDNS列表里了……
