DNS3: Authoritative Semantic Data via DNS

DNS3 is our open-source implementation of a DNS serving arbitrary (authoritative) metadata through DNSSEC taking advantage of Semantic Web technologies.

On this webpage we provide access to the entire source-code of our framework, a sample installation, and the ontology used to describe semantic information about internet domains in the TXT record of DNS responses.

Such an approach can be used to enable different end-user applications such as, domain information pre-fetching, malware detection, and domain suggestions piggybacking on DNS logs and the DNS infrastructure.
