Query on DHCP-to-DNS communications

["John M. Wobus" <[e-mail]>]

I would like to replace this text in the DHCP FAQ:

> 11. Can a DHCP client update its DNS entry through DHCP?
>
>     No. There has been some discussion about adding this ability to DHCP.

Here is my draft for the question and answer to replace this:

> 11. Can a DHCP client or server make a DNS server update the the
>     client's DNS entry to match the client's dynamically assigned
>     address?
>
>     There is no standard DNS interface to allow a DHCP client or
>     server to do this, but there are presently efforts to define such
>     a standard.  In the mean time, there are DNS and DHCP servers
>     that accomplish this through proprietary means.

I have written this so as to beg the question as to whether the DNS
will receive its information from the DHCP server, or from the DHCP
client.  My questions:

a) Has my clever phrasing left out a possible method that is receiving
   consideration?
   (The DNS server could poll the DHCP server once a second; or the
    DHCP client could kick the DNS server to ask the DHCP server for
    the current address; these ideas seem kooky to me, but I mention
    them because they do show that things could be accomplished in
    other ways)

b) Am I right in framing this as a "DNS enhancement"?  I.e., a standard
   interface will be added to the DNS, then the DHCP developers will
   implement it.

c) Is there more specific information that I could add?  E.g. perhaps
   it is now clear that the communication in question will be between
   the DHCP server and the DNS server.  (I seem to recall that IBM's
   solution was to have the client update the name & the server update
   the address)
