Summary: Ready

Major issues: None

Minor issues: None

Nits/editorial comments:
 - 1.2 page 6: highligts -> highlights

 - 3 page 8: RFC 6090 does not fully define ECDH because of the "compact"
  representation. Now it is a detail and if it can have an impact for
  implementors I think the security directorate will ask for a clarification
  (and in general I rely on the security directorate for all security
   related points, for instance whether DEX has a formal proof of its
   security properties)

 - 5.3.2 page 23: return-routablility -> return-routability

 - 4.1.1 page 11: I wonder if the puzzle solution check includes the
  check of the puzzle itself but the remark saying with K=0 the puzzle
  is just a retrun-routability cookie provided an answer... (so nothing
  to change)

 - at the exception of the Acknowledgments section you use the English
  spelling (with a 'e'): it is consistent with other HIP documents so
  I have no problem with this.

 - page 14: "and he system" -> "and the system"

 - 9 page 42: perhaps a SHOULD in "Thus, any signaling
      that indicates such anonymity should be ignored as explained in
      Section 1.1." ?

 - 9 page 43: computated -> computed

 - B page 50: IEDG -> IESG
