DNSSEC works by digitally signing records for DNS lookup using public-key cryptography.The correct DNSKEY record is authenticated via a chain of trust, starting with a set of verified public keys for the DNS root zone which is the trusted third party.
OpenDNSSEC was created as an open-source turn-key solution for DNSSEC. It secures DNS zone data just before it is published in an authoritative name server . OpenDNSSEC takes in unsigned zones, adds digital signatures and other records for DNSSEC and passes it on to the authoritative name servers for that zone.
C - Conflict. TC - TrunCation. T - Tentative. Z - Reserved for future use. RCODE - Response code. QDCOUNT - An unsigned 16-bit integer specifying the number of entries in the question section. ANCOUNT - An unsigned 16-bit integer specifying the number of resource records in the answer section.
On 32-bit systems only, installing drivers that are not validated with Microsoft is possible after agreeing to allow the installation at a prompt warning the user that the code is unsigned. For .NET (managed) code, there is an additional mechanism called Strong Name Signing that uses Public/Private keys and SHA -1 hash as opposed to certificates.
A wildcard DNS record is a record in a DNS zone that will match requests for non-existent domain names. A wildcard DNS record is specified by using a * as the leftmost label (part) of a domain name, e.g. *.example.com.
DNS-based Authentication of Named Entities (DANE) is an Internet security protocol to allow X.509 digital certificates, commonly used for Transport Layer Security (TLS), to be bound to domain names using Domain Name System Security Extensions ().

DNS over TLS (DoT) is a network security protocol for encrypting and wrapping Domain Name System (DNS) queries and answers via the Transport Layer Security (TLS) protocol. The goal of the method is to increase user privacy and security by preventing eavesdropping and manipulation of DNS data via man-in-the-middle attacks.
