Editing XDNS X ALIAS RR (section)

=== X-ALIAS-<RR> Records ===
The following four X-ALIAS-<RR> Records are supported:
* X-ALIAS-A
* X-ALIAS-AAAA
* X-ALIAS-MX
* X-ALIAS-TXT

You can use any of them to have all respective records of the reference zone copied over to your zone. Any changes to the respective records of the reference zone will be constantly monitored and your zone will be automatically updated accordingly if there are any changes. No additional lookups are made when your zone is queried so this is the high performance solution if you want to manage only one dedicated authoritative DNS zone but utilize the respective A, AAAA, MX or TXT records for as many other DNS zones as needed.

PLEASE NOTE: If you set a  X-ALIAS-<RR> xDNS record for your zone then all previously existing resource records of the same type and  will be removed and then the respective RRs from the reference dns zone will be set.

X-ALIAS-<RR> Records have the following syntax:
<pre>
yourdomain.com. <TTL> IN X-ALIAS-<RR> <REFERENCE-DNS-ZONE>
</pre>

PLEASE NOTE: The secluding dot after the domain name (www.yourdomain.com.) is required in any case!
