Hello libtool maintainers,

Our project uses the `libtool` package, which is vendored via `conan` as defined in this conancenter recipe [link to recipe]. Recently, all of our builds have been failing when attempting to build the `libtool` package for our target architecture. This is due to an inability to fetch the source code from `https://ftp.gnu.org/gnu/libtool`.

Many of our builds originate from the same public IP address (15.205.200.76), which fronts our corporate network. We suspect this IP address might be part of a larger CIDR block that has been blocked.

If this is the case, could you please allow-list our IP address, 15.205.200.76?

Thank you for your assistance.

Best regards,

Michael Fedell
