I find this confusing.

It specifies two ranges 0-15 and 0-1048575 the latter being subdivided 
into ranges 0-15 16-239 etc and then talks of the lower range and the 
higher range; is the higher range 0-1048575 or 16-239 or 16-1048575 or ...?
Lesser and greater or first and second or smaller and larger .. I might 
find unambiguous but reading this with an innocent eye, I find higher 
ambiguous.

And in Security, 'It does not effect the forwarding ...' Well, no, it 
would likely not affect it either:-)
