We do offer recursive / resolver DNS service, but only for companies who need to deploy it within their organization or for clients. We do not offer it generally speaking for single users. Single users are encouraged to take a look at OpenDNS if they need secure options, or perhaps even just use Google public DNS servers at 8.8.8.8 and 8.8.4.4.
If your organization is interested in a quote for recursive / resolver DNS, please contact us for further information.
