Regarding ADNSR Licensing and Region Support

[K.Kanbayashi]

Attention: Global TPM team,

I have several questions about the Advanced DNS Security Resolver (ADNSR) licensing and region support.

In the activation documentation, I noticed the instruction “Select a Region where you want to deploy your product.”Advanced DNS Security Resolver Activation

However, I could not find any documentation describing which regions ADNSR supports, unlike other services such as Device Security (which requires choosing an SLS ingestion region) or AIRS (which lists supported regions).
During ADNSR activation, a deployment region must be selected, but there is no information about whether:

• region choice affects ADNSR functionality,
• some regions do not support ADNSR, or
• the ADNSR region must match the Strata Logging Service (SLS) region.

Could you please clarify the following?

1. Does ADNSR have officially supported activation regions?
2. Are there any region‑specific feature limitations?
3. Should the ADNSR region match the SLS logging region?
