On Unixes this module calls the system \f(CW\*(C`ifconfig\*(C'\fR command to perform the actions.

OpenBSD: \f(CW\*(C`/sbin/ifconfig \-A\*(C'\fR command is not returning information about \s-1MAC\s0 addresses

MSWin32: \f(CW\*(C`GetAdaptersInfo\*(C'\fR function is not returning information about interface
which have address \f(CW127.0.0.1\fR binded
