I have read the document, and support publication (modulo very minor nits
that should be fixed).

In addition to these nits, I do have one further suggestion for Section 8.

I'm not sure if it is too late to make such a suggestion, but on reading
(and thinking about) the spec,
it could be useful guidance (particularly for clients which may not be
aware of changes to their Client-IP address):

"o   In order to determine that a Server has detected a change to the
Client-IP, a Client may consider
      a BADCOOKIE error sooner than would be expected from a Server Cookie
refresh as a signal
      that the Client-IP may have changed, and thus that a new Client
Cookie should be created for each Server."

Nits:
Introduction - I believe "provides" should be "provide", to agree with the
singular "is" of the verb. (Sorry, grammar nit.)

Section 1.1 - I believe all the "Section Section" instances should really
just be "Section".

Section 4 - "too frequent" -> "too frequently".

Section 4.3 - "in the anycast." -> "in the anycast set."

Section 4.4 - hash calculation, end of first line "Client-IP," ->
"Client-IP |"

Section 5 - "anycast group" -> "anycast set"; "us used" -> "is used"

Section 8 - "like for example five minute." -> "for example five minutes."
