on <https://cran.r-project.org/bin/windows/base/README.R-3.4.4> it says

"R 3.4.4 for Windows

This distribution contains a binary distribution of R-3.4.4 to run on
Windows XP and later (including 64-bit versions of Windows) on ix86
and x86_64 chips."

R i386 runs without problems on Windows XP up to and including version 3.4.2.
Only R i386 3.4.3 & R i386 3.4.4 cannot access the internet on my Windows XP.

I supposed this is not so much a problem with the OS (because "IdnToAscii" exists on WindowsXP SP3 as well), but rather with the header files and/or import libraries of the MinGW environment.

Perhaps it does not take too much effort to restore WindowsXP compatibility. The described symptoms are at least easy to debug.

I know that WindowsXP is no longer supported by Microsoft. However, I work in an academic environment and we are stuck to Windows XP on some computers because some of our data acquisition devices are only properly supported on that OS.

Regardless of your conclusion, I'm thankful to the R developer team to make the R software freely available to the scientific community.

With kind regards,
