DNS is a distributed and
hierarchical database: and whereever there is a hierarchy you need to have one (or several) "roots". These are the "tier-1-servers". To prevent flooding them with requests (which would make the DNS system slow overall) many organisations (including Google) have built "tier-2-servers" and offer their services to the public in various ways:
there are companies like OpenDNS which create some revenue redirecting you to a site they get money from under certain circumstances (like "host not found", etc.)
there are companies like Google which seemingly offer their service without any payment but they keep your DNS requests in a database and so over time know your surfing habits, which is marketable information
there are companies trying to restrict what you should see by denying name resolution for sites they think you should not see. Many of the DNS servers ISPs offer fall into this category but also Norton ConnectSafe and many other "safe" installments (note: "safe" just means "arbitrarily incomplete")
In light of this i suggest to use two nameservers from two different providers and only use providers which do not filter anything. My personal opinion is that i know best what i should see and if a website doesn't fall into that category i just avoid it. Seeing something i do not want to see for as long as it takes me to decide that won't kill me.
I use "censurfridns.dk" ( 89.233.43.71, 91.239.100.100), which is located in Denmark and it works to satisfaction. There are similar services in Austria ("FreeDNS", 37.235.1.174, 37.235.1.177) and probably some others you might find.
I hope this helps.
