I don't think & does what you want anyway.  It just does a bit AND on
the two addresses, it doesn't change the masklen property.

There's probably only a small number of distinct netmasks you actually
need to handle in this conversion.  What I'd suggest is writing a simple
function with a CASE statement to translate netmask to an integer mask
length, and then you can use set_masklen to merge that result into the
address value.
