Title: IPv4 routes with an IPv6 next hop
Reviewer: Karen O'Donoghue
Review result: Ready

# Overall

This is a short clearly written document. It provides a mechanism to route
IPv4 packets through an IPv6 next hop. It seems very straightforward given 
the limited scope of the document. 

# Security considerations

The security considerations section of this document is pretty short,
basically indicating that this document provides some additional 
flexibility and with that flexibility comes some security risks based 
on assumptions that network administrators could reasonably make. It doesn't 
do very much to address those risks, but it does identify the possibility of
those risks. The tools and processes used to manage networks using this 
mechanism would need to be appropriately updated to manage those risks.
