DNS record types and when to use them

by gotinobatko In reply to What are DNS record types ...

A Records

A Records are most commonly used to map a fully qualified domain name (FQDN) to an IPv4 address.

Example: A records can be configured in a domain for a specific host such as Example Domain or for the root record such as Example Domain.

AAAA Records

AAAA Records are similar to A records but point to IPv6 address instead of IPv4 address.

Example: IPv4 addresses are finite, while IPv6 was created to allow for an abundant amount of unique addresses.

CNAME Records

CNAME Records are alias record mapping FQDN to FQDN, multiple hosts to a single location without having to specifically assign an A record to each hostname.

ANAME Records

ANAME Records allow you to map the root of your domain to a hostname or FQDN. ANAME Records were developed by DNS Made Easy as a combination of CNAME and A Records, both RFC compliant and saving the extra DNS lookup. This is important because this allows you to have the functionality of a CNAME record at the root/apex of your domain.

SOA Records

SOA Records (Start of Authority) are used to records are used to direct how a DNS zone propagates to secondary name servers. An SOA record is created by default for each domain added into the Constellix DNS system.

NS Records

NS Records (Name Server) specify which name servers are authoritative for a domain or subdomain. NS Records are used in the event that another external DNS provider will be used in conjunction with Constellix DNS. They can also be used if a subdomain delegation takes place to external name servers.

MX Records

MX records use mail servers to map where to deliver emails for a domain. If no email is sent or received from a domain, then there is no reason to have MX records configured.

Just to give credit I got all of this information from Constellix they have a really good blog on dns record types check it out if you want some more info.

Another best practice is to have your own DNS (server.)
