CIDR range to download models

Hi Folks,

I work for an enterprise with a relatively locked down environment. We wanted to experiment with giving Data Scientists access to Huggingface models over public network. One possible solution is locking down public access to a set CIDR range for Huggingface Hub. Is there anyone from the Huggingface or otherwise that may know: 1. is this possible and 2. if yes - what is the CIDR range?
