Does anyone on this list know more about the way BIND is being amended to allow the “rewriting” of DNS answers? Jorge? Timothe?





Yes.  Recent versions of BIND (starting I think with 9.8) have a feature called RPZ = Response Policy Zone.  It is rather controversial.



The intent was to make it possible for enterprise customers to block websites (and other protocols relying on DNS) according to some policy - typically known malware and/or non-work sites.  It doesn't work with DNSSEC.  It has some potential for abuse by ISPs.  As ISC tells the story, this was implemented because of (bind) customer demand, not because ISC thinks it's a good idea.



Here are some references:

I will refrain from editorial comment - except to note that DNS is not a particularly good place to implement a blocking policy.

Hi

As discussed on our call the other night, some of the key developments from a global public interest standpoint go beyond GNSO & ICANN policies but we might still consider whether there's grounds for useful NC engagement…
