What types of DNS records are available?

There are different types of DNS entries depending on the type of use:


A records stand for a host entry, e.g., www. and refer to an IP address of a server e.g. Web server.

Example: The domain has an A-record that points to the IP address


AAAA stands for the same type of entry as for the "normal" "A" record, but this entry is intended to use IPv6 addresses. When using IPv6, this entry has priority over the normal "A" entry.

Example: The domain has an AAAA record pointing to the IPv6 address f3b0:1:cb3a:b4b0:7872:5ef9:93bb:e7a2.


ALIAS / ANAME Records have the same purpose as CNAME Records, but are technically different. It is about assigning an IP to the domain via a host name. They allow e.g., refer the root record in the domain to a destination host name.

Example: The domain has an ALIAS record pointing to the hostname


This DNS entry is used if the hostname should be referenced instead of an IP address. CNAME entries, unlike ALIAS / ANAME entries, can only be used with subdomains.

Example: The subdomain has a CNAME record pointing to the hostname

MX Record

MX Records are responsible for specifying a domain one or more mail servers with priority (10, 20, 30, etc.). The lowest value is the first mail server to use.

Example: For the domain there is an MX entry pointing to the easyname mail server

NS records

NS records are used to set a name server for a single domain.

Example: For the domain an NS entry is set which points to the easyname name server

SRV records

SRV records allow the definition of the availability of IP-based services offered under a domain and are required for the use of certain services and applications such as SIP / VoIP or XMPP (Office 365, Jabber, Instant Messaging, etc). You can also specify the port and the protocol via an SRV entry.

Example: For an SRV entry is set to use the SIP service with the TLS protocol. This entry points to the hostname 443

TXT records

TXT records contain freely selectable text. On some systems, the content is used to encode administrative data. TXT records are also used to create an SPF entry.

Example: For the domain there is a TXT entry with the following content: "v = spf1 include: -all"
