OARC has strict policies and processes in place, set out in the DNS-OARC Data Sharing Agreement to limit access to this data to bona-fide OARC Members and researcher Participants. A: It's true that open resolvers are usually considered to be a problem and have been used — in combination with source address spoofing — to conduct large-scale DDo S attacks.Such attacks are made possible because (1) there are hundreds of thousands, if not millions, of open resolvers, and (2) their owners/operators are unaware of the openness.A: In line with OARC's mission, query data from our various testbed resolvers is logged and stored for non-commercial, public benefit research purposes.Users of the service should be aware this may include personally identifiable information.ODVR has been configured with the following list of trust anchors: OARC collects data from the ODVR nameservers and makes this data available to our members for research purposes.These graphs, updated nightly, show the number of queries received with and without the "DO" bit set, and the number of responses sent with and without the "AD" bit set. Chances are that, for most of your DNS queries, there will not be any DNSSEC signatures.In this guide we’ll cover how to secure your C# / ASP.

If we have reason to suspect abuse of the ODVR nameservers, we will act quickly to stop it.

Generally, this should not be your motivation for using ODVR.

If you are stuck using a DNS resolver with poor source port randomization then ODVR may make you more secure.

To fix this problem we recommend adding an extra check in your filter attribute, like so, telling it to only reject incoming requests if your app is running in production.

Validating requests to your Twilio webhooks is a great first step for securing your Twilio application.

4 October 2010 UPDATE: We have now added the DNSSEC Testbed to both resolvers.
