For the longest time I have been a big fan of using OpenDNS‘ DNS servers. For any of you that are not familiar, you can point your DNS to their servers (18.104.22.168 & 22.214.171.124) and have about perfect domain name resolution. With some ISPs that I can name, this is a huge benefit. Also with their free DNS, you can manage a blacklist and whitelist from their site. Also available from their dashboard is the option to use their precompiled denied categories, e.g. pornography, drugs, etc.
Recently I came across other open DNS servers that were about 3x faster (for me), but they don’t contain any of the great features that OpenDNS supplies. The other DNS servers are: 126.96.36.199 – 188.8.131.52. Using traceroute I found that I reach all these 4.2.2.x servers in only 7 hops (~18ms) while I reach the OpenDNS servers in 15 hops (~50ms).
Since in my household a blacklisting option is a great plus, I decided to keep the OpenDNS servers enabled on the desktop machines and the router. On the other hand, my laptops and servers are now pointing to the newly found 4.2.2.x servers.
