+## DNS entries for a parked domain that does not send emails but has a website
+
+| Hostname | Type | TTL | Data |
+|:------------:|:----:|:----:|:-------------:|
+|      `@`     | `MX` |`1800`|`0 .`          |
+|      `@`     | `TXT`|`1800`|`"v=spf1 -all"`|
+|`*._domainkey`| `TXT`|`1800`|`"v=DKIM1; p="`|
+|    `_dmarc`  | `TXT`|`1800`|`"v=DMARC1;p=reject;sp=reject;adkim=s;aspf=s;fo=1;"`|
+
+### DNS entries explained
+
+#### Null MX
+Explicitly configure an 'empty' MX record according to [RFC7505](https://tools.ietf.org/html/rfc7505).
+```
+example.com. IN MX 0 .
+```
+
+#### SPF
+Set an an empty policy and a hard fail.
+
+```
+example.com. IN TXT "v=spf1 –all"
+```
+
+#### DKIM
+
+```
+*._domainkey.example.com. IN TXT "v=DKIM1; p="
+```
+
+#### DMARC
+Set DMARC policy to reject mails, but allow reporting to take place. 
+```
+_dmarc.example.com. IN TXT "v=DMARC1; p=reject; rua=mailto:rua@example.com; ruf=mailto:ruf@example.com"
+```
+
+## DNS entries for a parked domain that does not send emails
+
+* Don't use an `A` or `AAAA` record for parked domains;
+* Don't redirect from parked domain `example.com` to the used domain `example.org`, since this encourages users to keep using the parked `example.com`. If a redirect is desirable, make sure to use the proper redirect order in order for HSTS headers to remain effective:
+	* redirect `http://example.com` to `https://example.com`
+	* when using `HTTPS`, redirect `https://example.com` to `https://example.org`.
