Rotating between a handful of providers could be a net negative for privacy:
- every FQDNs you resolve is leaked to at least one provider
- the FQDNs you resolve often (e.g. every day) are leaked to at all the backend providers over time
If you want to protect your privacy you need DNS resolution over Tor.
- JoshTriplett 5y agoWhile I agree that rotating might be a net negative, that particular issue could be worked around: hash the FQDN and use the hash to determine which provider you use, so that a given user always resolves a given FQDN with the same provider. (Salt the hash, so that different users use different providers for that FQDN.) It's still not clear if it's a win to rotate, but if you were going to rotate, that would help.
- goodpoint 5y agoThat's not rotation, by definition. (and hardly beneficial for privacy: you just divided the FQDNs you leak across 3-4 providers)
- JoshTriplett 5y agoThe only advantage would be in reducing the ability to correlate a user's sites. But nonetheless, I agree.
