To add and manage these records through Gandi’s interface and API, please note that your domain must be using Gandi’s LiveDNS nameservers. ALIAS records are not comptable with Gandi’s Classic nameservers (a.dns.gandi.net, b.dns.gandi,net, c.dns.gandi.net).
When do I use an ALIAS record?¶
You will use an ALIAS record when you want the domain itself (not as subdomain) to “point” to a hostname.
This is useful, just like with CNAME records, if you want to point to a hostname instead of an IP address.
Since it is not possible to use a CNAME record on just the bare domain (“example.com”), the “ALIAS” record type is a solution to that problem.
When using an ALIAS record, please note that:
- There can not already be an A or AAAA record on the bare domain (@).
- An ALIAS record will break DNSSEC on the bare domain (@), because @ A and @ AAAA responses will be missing the RRSIG records, which will break resolution on all resolvers.
Can I have an example?¶
Here is an example:
@ 10800 IN ALIAS example.example.com.
Please note the final dot (.) at the end is necessary for the record to work correctly.
