Which DNS Record types does Oracle Cloud Infrastructure DNS support?
Currently, Oracle Cloud Infrastructure DNS supports the following DNS records:
• A (Address Record)
• AAAA (IPv6 Address Record)
• CNAME (Canonical Name Record)
• NS (Name Server record)
• MX (Mail Exchange Record)
• PTR (Pointer Record)
• SOA (Start of Authority Record)
• SRV (Service Locator)
• TXT (Text Record)
In addition, Oracle Cloud Infrastructure DNS supports an ALIAS record type which is specific to Oracle Cloud Infrastructure DNS. It can be used to map to various Oracle Cloud Infrastructure services (Compute, Network, Database or Storage), third party or private assets. The ALIAS record acts similar to a CNAME record, with the difference being they can be at the ‘apex’ record of a Zone and is not visible to external resolvers. ALIAS record types support only A and AAAA queries. Any DNS query is resolved to the mapped asset. E.g., if “example.com’ is queried, the ALIAS record would resolve to the mapped asset (for example Oracle Cloud Infrastructure Compute asset). ALIAS records also help by not having to map a record to a specific IP address as IP addresses associated with certain assets could dynamically change due to various conditions.
