oh b*%%*r. This might be why the ACLARP originally used raw bytes instead
of proper types.
Are you able to add a cast it to DWORD->BYTE[4]->in_addr or
DWORD->BYTE[4]->int->in_addr or even void* if those fail?

I think we need to check the byte-order is not touched. It should be
arriving as a network-order DWORD.
