[1] The free DNS servers listed above as Level3 will automatically route to the nearest DNS server operated by Level3 Communications, the company that provides most of the ISPs in the US their access to the Internet backbone.

[2] Google also offers IPv6 public DNS servers: 2001:4860:4860::8888 and 2001:4860:4860::8844.

[3] OpenDNS also offers DNS servers that block adult content, called OpenDNS FamilyShield. Those DNS servers are 208.67.222.123 and 208.67.220.123. A premium DNS offering is also available, called OpenDNS Home VIP.

[4] The Norton ConnectSafe free DNS servers listed above block sites hosting malware, phishing schemes, and scams, and is called Policy 1. Use Policy 2 (199.85.126.20 and 199.85.127.20) to block those sites plus those with pornographic content. Use Policy 3 (199.85.126.30 and 199.85.127.30) to block all previously mentioned site categories plus those Norton deems “non-family friendly.” Be sure to check out the list of things blocked in Policy 3 – there are several controversial topics in there that you may find perfectly acceptable.

[5] GreenTeamDNS “blocks 18 categories which include malware, botnets, dangerous websites, adult related content, aggressive/violent sites as well as advertisements and drug-related websites” according to their FAQ page. Premium accounts have more control.

[6] Register here with SafeDNS for content filtering options in several areas.

[7] The DNS servers listed here for OpenNIC are just two of many in the US and across the globe. Instead of using the OpenNIC DNS servers listed above, see their complete list of public DNS servers here and use two that are close to you or, better yet, let them tell you that automatically here. OpenNIC also offers some IPv6 public DNS servers.

[8] These Public- DNS servers are the only two currently operating in the United States but if you’re located ouside the US, see their complete list here and choose the best servers based on your location.

[9] FreeDNS says that they “never log DNS queries.” Their free DNS servers are located in Austria.

[10] The censurfridns.dk DNS servers are uncensored, operated by a privately funded individual, and are physically located in Denmark. You can read more about them here. IPv6 DNS servers are also available at 2002:d596:2a92:1:71:53:: and 2001:67c:28a4::.

[11] DNS.WATCH also has IPv6 DNS servers at 2001:1608:10:25::1c04:b12f and 2001:1608:10:25::9249:d69b. In an uncommon but much appreciated move, DNS.WATCH publishes live statistics for both of their free DNS servers. Both servers are located in Germany.

[12] Hurricane Electric also has an IPv6 public DNS server available: 2001:470:20::2.

[13] puntCAT is physically located near Barcelona, Spain. The IPv6 version of their free DNS server is 2a00:1508:0:4::9.

Note: Primary DNS servers are sometimes called preferred DNS servers and secondary DNS servers are sometimes called alternate DNS servers. Primary and secondary DNS servers can be “mixed and matched” to provide another layer of redundancy.

Bạn nên dùng 1 DNS của Open DNS là 208.67.220.220 (hoặc Google 8.8.8.8) và 1 của nhà mạng bạn thích (mình đang dùng của VNPT là 203.162.4.1) để lướt web nhanh hơn
Ưu điểm của Open DNS:
– Hỗ trợ nhiều ISP (nhà cung cấp)
– Thông minh (nếu lỡ có gõ địa chỉ sai thì cũng biết nội suy ra địa chỉ đúng)
– Máy chủ mạnh, an ninh cao (dĩ nhiên, nếu bạn thấy chán cái cảnh DNS của mình cứ die up die down – chết lên chết xuống) 

Nhực điểm : đó là dùng thì lướt web đã thật nhưng thỉnh thoảng cũng hay bị delay ( chậm )
