AKAMAITLC

AKAMAITLC is a proprietary Top-Level CNAME (TLC) record type specific to Akamai Edge DNS. It allows CNAME-like functionality at the zone apex (@) of a domain where regular CNAME records are not permitted.

The difference between AKAMAITLC and CNAME is that AKAMAITLC records are resolved by Akamai Edge DNS servers instead of the client's resolver. This is similar to how AKAMAICDN records work, except that AKAMAITLC records can be pointed to any domain, not just Akamai properties. If you are pointing to an Akamai property, you should use AKAMAICDN instead.

Important restrictions:

• Can only be used at the zone apex (@)

• Limited to one AKAMAITLC record per zone

• Cannot coexist with an AKAMAICDN record at the apex

The answer_type parameter controls which record types are returned when clients resolve the target:

• DUAL: Returns both IPv4 (A) and IPv6 (AAAA) records

• A: Returns only IPv4 records

• AAAA: Returns only IPv6 records

Example

dnsconfig.js

D("example.com", REG_MY_PROVIDER, DnsProvider(DSP_MY_PROVIDER),
    // Redirect example.com to google.com, returning both A and AAAA records
    AKAMAITLC("@", "DUAL", "google.com."),
);
