The perl code that you provided runs with no complaints on my machine.

This is perl 5, version 24, subversion 0 (v5.24.0) built for MSWin32-x86-multi-thread-64int

If I try to install the Socket module, I am told:

Socket is up to date (2.021).

If I look in C:\Strawberry\perl\lib\auto\Socket\, I see:

Socket.xs.dll

Upon further research, I find that the Socket module is in the list of Perl core modules.
