What are the DNS records?
DNS records (aka zone files) are instructions that live in authoritative DNS servers and provide information about a domain including what IP address is associated with that domain and how to handle requests for that domain. These records consist of a series of text files written in what is known as DNS syntax.
What is DNS a AAAA record?
quad A Record
An AAAA Record (quad A Record) is another type of DNS Record that points a domain or subdomain to an IPv6 address, so that when someone types that domain or subdomain in the address bar, the browser knows where to go.
What is the difference between and A and AAAA record in DNS?
A and AAAA records are equally important when it comes to resolving DNS. The difference lies in that A records is used to resolve a hostname which corresponds to an IPv4 address, while AAAA records are used to resolve a domain name which corresponds to an IPv6 address.
What is the purpose of Dane?
DANE (DNS-based Authentication of Named Entities) is the option to use secured DNS infrastructure to store generic verifiable information for multi-factor verification.
What is a PTR record used for?
A PTR (or Pointer) record is a security tool. Essentially, when you receive an email, your mail server uses the PTR record that comes in with the email message to check that the mail server sending the email matches the IP address that it claims to be using. This is also known as “reverse DNS lookup”.
What is DNS and DNS record types?

In general, there are two ways of resolving a host or a domain name to an IP address, using the domain name system – a Recursive query and a non-Recursive query. The Recursive query is, when a DNS client directly gets the IP address of a domain, by asking the name server system to perform the complete translation.

Difference Between A and CNAME An A Record maps a hostname to one or more IP addresses, while the CNAME record maps a hostname to another hostname.
What is the difference between a record and CNAME?
These are the main differences: The A record maps a name to one or more IP addresses when the IP are known and stable. The CNAME record maps a name to another name. It should only be used when there are no other records on that name.
What are some examples of DNS records?
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 lookups (PTR), and domain name aliases ( CNAME ).
What are the different types of DNS records?
Type of DNS records. There are many different types of DNS records out there, the most common ones are A, NS, MX, TXT, SOA, and CNAME, however, there are others who are very important for our daily tasks as systems administrators or DevOps engineers.

There are 5 types of DNS records: A, CNAME, NS, MX, and PTR A records. Address (A) records direct a hostname to a numerical IP address. For example, if you want mycomputer.yourdomain.com to point to your home computer (which is, for example, 192.168.0.3), you would enter a record that looks like: mycomputer.yourdomain.com. A 192.168.0.3
