Free, secure and smart dns with OpenDNS

Recent surf activity sent me to interesting website, OpenDNS

What is OpenDNS?

OpenDNS helps you navigate the Internet in a safer, faster, smarter and more reliable way. Our service is free and requires nothing to download. OpenDNS doesn’t replace your existing Internet connection, it just makes it better.

Important useful things for me (taken from their FAQ) :

Why is OpenDNS safer than what I’m using now for DNS?

OpenDNS intercepts phishing attempts. OpenDNS customers will be warned if they attempt to visit a phishing site.

Why is OpenDNS faster than other DNS services?

Two things make OpenDNS faster than similar services. First, OpenDNS runs a really big, smart cache, so every OpenDNS user benefits from the activities of the broader OpenDNS user base. Second, OpenDNS runs a high-performance network which is geographically distributed (see network map) and serviced by several redundant connections. OpenDNS responds to your query from the nearest location. That means we’re very fast (and extremely reliable, to boot).
