R help - Nov 2025 - Request for List of URLs Needed for R Package Installation

Dear R Team,

I am currently setting up R in the Bank of Baroda environment, and as part
of the security process, I need to request whitelisting of all URLs/domains
required for installing R packages (including dependencies).

To complete this request, I kindly ask you to please share the *full list
of URLs, domains, CRAN/Bioconductor mirrors, GitHub links, and any other
repositories* that R connects to during installation and updating of
packages.

Once I receive the list, I will forward it to the Network/IT Security team
for whitelisting.

Requesting your support in providing this information at the earliest.

Thank you.

Regards,
*Jyoti Prajapati*

That's a tall order.

I'm no expert, but I believe you can specify what CRAN mirror to use
when obtaining packages. I don't know if an institution could restrict a
user to using just one of them.

Here is a list of CRAN mirrors:

I've never used Bioconductor, but here is a list of mirrors:
