Zusammenfassung

SRV records, DNSSEC, and DANE among others fortify the Domain Name System as the central information hub behind the Internet. Largely hidden from the user, an increasing number of protocol and trust decisions are contingent on DNS. Neglect or attacks on DNS have much more impact today than ever, now endangering security far beyond denial of service. Opportunistic Persistent DNS (opDNS) addresses these problems by abandoning pessimistic caching and eliminating unnecessary traffic. Today's DNS infrastructure relies on the hosts forgetting and refreshing DNS records in relatively short time. In conjunction with TLS, opDNS greatly reduces the number of queries and in turn increases privacy, reliability, and efficiency. Even with DNS lookups all but eliminated for frequently visited secure services, changes to the server addresses will be recognized almost immediately, unlike standard DNS. We will show how end systems can take advantage of opDNS without having to wait for support by server operators or application developers, enabling the most effective way of deployment.
