Some comments:

1) BGP Security Concerns

        The primary security concern that needs to be addressed is the
incentive to hijack legitimate IP address blocks via BGP spoofing.

        This is something the IAB should consider as a matter of urgency.
The only proposal made in the area (Kent) is undeployable, it requires
adding IPSEC to every router on the backbone which ain't happening and is
not necessary.

        It is very clear that the ISPs will be deploying IP based
authentication schemes in the near future regardless of concerns raised by
the IETF.

2) DNS Security Concerns

        The DNS statement is incorrect. The DNS does have security, it just
is not very good and it is not cryptographically based.

        The cookie mechanism is limited to a 16 bit cookie. This could be
easily extended to 128 bits by means of a dummy resource request.

        DNSSEC is undeployable as currently specified. The IESG is aware of
this issue.

3) We do not need yet another IP authentication scheme.

        At this point proposing yet another scheme based on the same
principles does not contribute to the discussion.
