Subject: [DNSOP] Malformed response to EDNS option

I'm seeing a malformed response to EDNS options from the name servers for atdmt.com, e.g.

dig +nsid clk.atdmt.com @glb04.aquantive.com

reports

;; Warning: Message parser reports malformed message packet.
;; WARNING: Messages has 95 extra bytes at end

The problem seems to be triggered by any EDNS option in the request ( not specific to nsid ).

Any idea what is going on here?

Can anyone identify the apparently erroneous name server software?
