用联通dns时,不存在的域名会指向联通的导航页,浏览器里输一下就知道了

执行 set type=ptr 才有意义呀, 而且并不是每个 IP 地址都有对应的 PTR 记录.
例如: 8.8.8.8.in-addr.arpa name = google-public-dns-a.google.com. 114.114.114.114.in-addr.arpa name = public1.114dns.com. ( http://en.wikipedia.org/wiki/List_of_DNS_record_types ) |

用v2ex的
nslookup non.existent.domain Server: 178.79.131.110 Address: 178.79.131.110#53 Non-authoritative answer: Name: non.existent.domain Address: 178.79.131.110 用个google的 nslookup non.existent.domain Server: 8.8.8.8 Address: 8.8.8.8#53 ** server can't find non.existent.domain: NXDOMAIN 通过DNS查询不存在的域名的返回可以判断DNS污染 具体在 https://code.google.com/p/openwrt-gfw/wiki/AntiDNSPoisoning |
