i should have known that if it wouldn't access unaligned structure members
it wouldn't access unaligned structures either.  your fix is better, and will
be committed shortly.  (note that i only use sizeof(x) when x is a type name,
so i changed your "sizeof(dns)" to "sizeof dns" this time.)

noone has any feedback about my CLI questions?  can i just call this V1.0?
