# Introduction
|
||
This how-to is created by the Dutch Internet Standards Platform (the organization behind [internet.nl](https://internet.nl)) and is meant to provide practical information and guidance on explicitly configuring a parked domain not to use e-mail.
|
||
|
||
# What is a parked domain?
|
||
[Domain parking](https://en.wikipedia.org/wiki/Domain_parking) is the registration of an Internet domain name without that domain being associated with any services such as e-mail or a website.
|
||
|
||
## Domain without e-mail
|
||
If a domain is not using e-mail it is recommended to use the following settings.
|
||
|
||
### Null MX
|
||
Explicitly configure an 'empty' MX record according to [RFC7505 ](https://tools.ietf.org/html/rfc7505).
|
||
|
||
`example.nl IN MX 0 .`
|
||
|
||
### DMARC
|
||
Set DMARC policy to reject mails, but allow reporting to take place. This helps detecting activity related to your domain.
|
||
|
||
`_dmarc IN TXT "v=DMARC1; p=reject; rua=mailto:rua@example.nl; ruf=mailto:ruf@example.nl`
|
||
|
||
### DKIM
|
||
|
||
`*._domainkey IN TXT "v=DKIM1; p="`
|
||
|
||
### SPF
|
||
|
||
`example.nl IN TXT "v=spf1 –all"`
|
||
|
||
## Domain without a website
|
||
* Don't use an A or AAAA record for parked domains.
|
||
* Don't redirect from a parked domain to the used domain, since this encourages users to keep using the parked domain name. If a redirect is desirable, make sure to use the proper redirect order in order for HSTS headers to remain effective:
|
||
1. redirect from HTTP to HTTPS on the same (sub)domain.
|
||
2. when using HTTPS, redirect to another (sub)domain.
