What is a DNS Zone?
What is a DNS zone? What is its purpose? How is it accessed? And why? These are all excellent questions that deserve simple answers. To understand, there’s nothing like a definition.
The acronym DNS comes from English and stands for “Domain Name System,” which essentially represents record fields in a database underlying a Domain Name. This database allows information to be registered to indicate and direct a request or query to the appropriate destination. So, the DNS zone: what is it? Here are the main records it concerns:
DNS Zone Records
A Record – (Address Record): This field associates a Domain Name with an IPv4 IP address. It is the most commonly used record in the DNS zone to direct a Domain Name to an IP address.
AAAA Record – (IPv6 Address Record) : Similar to the A record, this field is used to associate a Domain Name with an IPv6 address, which is gradually becoming the new standard for Internet IP addresses.
CNAME Record – (Canonical Name): This field is actually an alias for an A record. It allows a Domain to be known by multiple Domain Names. This record is very useful for services that frequently change IP addresses.
MX Record – (Mail Exchange): The function of this record is to indicate to mail servers the path to take to ensure the reception of emails for a Domain Name by mail services.
NS Record – (Name Server): This record designates the servers where Domain Names wish to indicate their place of residence. These servers are responsible for providing DNS information for the specified Domain.
PTR Record – (Pointer Record): Used for reverse resolution, associating an IP address with a Domain Name. Primarily, this record is used in the context of configuring public IP addresses.
SOA Record – (Start of Authority): Contains information about the DNS Zone, including the primary server identifier, the DNS Zone administrator’s email, the DNS Zone file version, etc.
TXT Record – (Text): This field contains arbitrary text associated with a Domain Name. The TXT record is often used to store textual information, such as verification keys for SPF (Sender Policy Framework) services for email management.
SRV Record – (Service): The function of the SRV record is to specify the location of available services within the Domain. Primarily, this field is used for communication services such as Voice over IP (VoIP).
SPF Record – (Sender Policy Framework): Used to specify the authorized servers for sending emails for a Domain Name. By adding the appropriate information to this field, the Domain Name improves the email communication experience by contributing to the fight against unwanted emails (Spam) and verifying email authenticity.
Each record in the DNS Zone plays a very specific role for a Domain Name to specify a management function that concerns various aspects related to connectivity, messaging, security, and other online services necessary for an organization.
