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.
A DNS name server is a server that stores the DNS records for a domain; a DNS name server responds with answers to queries against its database. The most common types of records stored in the DNS database are for start of authority ( SOA ), IP addresses ( A and AAAA ), SMTP mail exchangers (MX), name servers (NS), pointers for reverse DNS ...
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 ...
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 ...

A Canonical Name ( CNAME) record is a type of resource record in the Domain Name System (DNS) that maps one domain name (an alias) to another (the canonical name). [1] This can prove convenient when running multiple services (like an FTP server and a web server, each running on different ports) from a single IP address.
