What IPs/subnets should we enable on our firewalls to have access to the Azure SMT servers?
I see these 2 lines in /etc/hosts on one of the servers, but I’m not sure what are all possible IPs for the SMT…

Hello,
Please refer to this blog post: [https://www.suse.com/c/riddle-me-this/](https://www.suse.com/c/riddle-me-this/)
You can get the list of all registration server IPs by running: `pint microsoft servers --smt`
HTH, Ivan.

Thanks for the info. That query doesn’t return anything for Azure US Gov regions. Does that mean you don’t have separate SMT servers for those?
