I am currently testing out the OpenDNS DNS service for one of the schools I work with.
it is a 'free' service ( income generated by advertising) and they provide two dns IP's for free usage which supposedly is faster than most dns lookups.
Also, again free, you can start an account and modify settings for content filtering, keeping users from accessing a variety of types of websites.
You can integrate this into your existing local DNS/LAN reduce the physical hardware by not needing a filter like Dansguardian, etc.. on premises, using OpenDNS instead.
We will be testing this service for the next thirty days on a private network before deciding if it is worth implementing on the school network.
stay tuned for more in depth and ongoing review.
