`DOMAIN_ELSEWHERE_AUTO()` is similar to `DOMAIN_ELSEWHERE()` but instead of
|
|
a hardcoded list of nameservers, a DnsProvider() is queried.
|
|
|
|
`DOMAIN_ELSEWHERE_AUTO` is useful when you control a domain's registrar but the
|
|
DNS zones are managed by another system. Luckily you have enough access to that
|
|
other system that you can query it to determine the zone's nameservers.
|
|
|
|
For example, suppose you own a domain but the DNS servers for it are in Azure.
|
|
Further suppose that something in Azure maintains the zones (automatic or
|
|
human). Azure picks the nameservers for the domains automatically, and that
|
|
list may change occasionally. `DOMAIN_ELSEWHERE_AUTO` allows you to easily
|
|
query Azure to determine the domain's delegations so that you do not need to
|
|
hard-code them in your dnsconfig.js file.
|
|
|
|
For example these two statements are equivalent:
|
|
|
|
```js
|
|
DOMAIN_ELSEWHERE_AUTO("example.com", REG_NAMEDOTCOM, DSP_AZURE);
|
|
|
|
// ...is equivalent to...
|
|
|
|
D("example.com", REG_NAMEDOTCOM,
|
|
NO_PURGE,
|
|
DnsProvider(DSP_AZURE)
|
|
);
|
|
```
|
|
|
|
NOTE: The `NO_PURGE` is used to prevent DNSControl from changing the records.
