Address record. Returns a 32-bit IPv4 address, most commonly used to map hostnames to an IP address of the host, but it is also used for DNSBLs, storing subnet masks in RFC 1101, etc. AAAA. 28. RFC 3596 [2] IPv6 address record. Returns a 128-bit IPv6 address, most commonly used to map hostnames to an IP address of the host.
DNS resolvers use NSEC records to verify the non-existence of a record name and type as part of DNSSEC validation. NSEC3 (next secure record version 3) Contains links to the next record name in the zone (in hashed name sorting order) and lists the record types that exist for the name covered by the hash value in the first label of the NSEC3 ...

DNS Certification Authority Authorization ( CAA) is an Internet security policy mechanism that allows domain name holders to indicate to certificate authorities whether they are authorized to issue digital certificates for a particular domain name. It does this by means of a "CAA" Domain Name System (DNS) resource record .
PPTP. WireGuard. v. t. e. 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 ( DNSSEC ). [1] It is proposed in RFC 6698 as a way to authenticate TLS ...
DNS zone. A DNS zone is a specific portion of the DNS namespace in the Domain Name System (DNS), which a specific organization or administrator manages. A DNS zone is an administrative space allowing more granular control of the DNS components, such as authoritative nameserver. The DNS is broken up into different zones, distinctly managed areas ...
In computer networks, a reverse DNS lookup or reverse DNS resolution ( rDNS) is the querying technique of the Domain Name System (DNS) to determine the domain name associated with an IP address – the reverse of the usual "forward" DNS lookup of an IP address from a domain name. [1] The process of reverse resolving of an IP address uses PTR ...
A domain validated certificate ( DV) is an X.509 public key certificate typically used for Transport Layer Security (TLS) where the domain name of the applicant is validated by proving some control over a DNS domain. [1] Domain validated certificates were first distributed by GeoTrust in 2002 before becoming a widely accepted method.
