In this case, using Storable probably isn't worth the trouble, given
1. The 16- and 32-bit fields are in network byte order, whereas
Storable assumes host byte order.
2. If you want to read certain IP options (e.g. record route), you
need to read unaligned words.
It would be simpler to just read bytes, and piece them together
