Hi team,

I have a question about the URLs used to download models from Ollama.
It appears that models are downloaded from links like https://.r2.cloudflarestorage.com/....

Could you please clarify the following points?

Does the subdomain change each time I download the same model, or is it fixed per model?
Do different models always use different subdomains, or can the same subdomain be used for multiple models?
For network whitelisting purposes, is it safe to allow *.r2.cloudflarestorage.com, or are there cases where the download domain list is more limited or static?

Thank you very much for your support!
