It is always an iffy proposition to open a bug in the CPAN RT (https://rt.cpan.org/Ticket/Display.html?id=179191) when all the unresolved tickets for a module are years old and all the resolved ones are far older.
Anyway: if the latest Net::CIDR::Lite update broke your use of it, apply the simple fix in that ticket. Who knows when it will actually get addressed in the canonical version…
