# Non-IETF DNS standards
|
|
|
|
* RPZ:
|
|
Response Policy Zone is a framework for blocking, dropping queries or
|
|
spoofing responses based on domain names, response IP addresses or
|
|
nameservers used during resolution. It has long lived as an [ISC Technical
|
|
Note](https://ftp.isc.org/isc/dnsrpz/isc-tn-2010-1.txt), and failed to become an IETF standard. It is nevertheless very
|
|
useful, and there is an industry of RPZ providers. Policies are described
|
|
by zones and are typically transmitted over IXFR.
