5. Types of DNS records
When creating or changing DNS records, you can choose between various types. Here is a list of the available types along with a description:
A-record
Maps a domain to a specific IP address.
| Option | Description |
|---|---|
| Host |
The (sub)domain you want to redirect. Example: www. |
| Type |
A |
| TTL (Time To Live) |
How long this DNS record remains valid in the cache of a name server. Example: 1 hour |
| Value |
The target of the DNS record. In the case of an A-record, this must always be an IP address. |
CNAME record
link from a subdomain with another subdomain. An alias for a domain name.
| Option | Description |
|---|---|
| Host |
The (sub)domain you want to redirect. Example: www. |
| Type |
CNAME |
| TTL (Time To Live) |
How long this DNS record remains valid in the cache of a name server. Example: 1 hour |
| Value |
The target of the DNS record. Example: www.website2.com |
MX-Record
Redirects email traffic from a domain to another email server. Defining a hostname as the designated mail server with a certain priority required.
| Option | Description |
|---|---|
| Host |
The (sub)domain you want to redirect. Example: mail. |
| Type |
MX |
| TTL (Time To Live) |
How long this DNS record remains valid in the cache of a name server. Example: 1 hour |
| Priority |
The priority assigned to this record with respect to the other MX records. Example: 10 |
| Value |
The hostname of the mail server. Example: mail.provider.com |
TXT record
TXT records can be used to save additional information in the name-server settings for a domain. The text is user-definable. This lets you include information to a name-server record when the information cannot be assigned to any specific record type. TXT records are therefore especially well-suited for special, custom configurations and the use of new services at the name-server level for which there is no specific record type available.
Here you can also add SPF records (Sender Policy Framework on Wikipedia).
| Option | Description |
|---|---|
| Host |
The (sub)domain you want to redirect. Example: mail. |
| Type |
TXT |
| TTL (Time To Live) |
How long this DNS record remains valid in the cache of a name server. Example: 1 hour |
| Value |
User-definable text. Example: test |
SRV record
Service resource records (SRV) can redirect IP-based services with a specific port to the desired server that provides this service.
| Option | Description |
|---|---|
| Host |
Service & log Preceded by an underscore (_) Example: _ldap._tcp |
| Type |
SRV |
| TTL (Time To Live) |
How long this DNS record remains valid in the cache of a name server. Example: 1 hour |
| Priority |
The priority assigned to this record with respect to the other SRV records with the same service. Example: 10 |
| Weighting |
The weighting given to this record within the same priority level of the same service. This is used for load balancing. Example: 0 |
| Port |
TCP or UDP port of this service. |
| Value |
The hostname of the server providing this service. Example: ldap.provider.com |
6. Finish
