Abstract
A response to a Domain Name System (DNS) query can be protected with authentication information to be used by a host that originated the query. In one example, a DNS server is not among servers that can be authenticated by the Domain Name System Security Extensions (DNSSEC). The DNS server generates a public-private key pair and uses the private key for signing DNS resolutions. The corresponding public key can be distributed to hosts that will communicate with the DNS server. In various implementations, the public key is distributed by the DNS server and/or routers or as part of a neighbor discovery interaction. In one example, the public key is distributed in certificate path advertisements of the IPv6 Secure Neighbor Discovery Protocol (SEND) protocol.
