Network Working Group M. Andrews Internet-Draft ISC Expires: April 8, 2013 October 5, 2012 Add 100.64/10 prefixes to Locally-Served DNS Zones registry. draft-andrews-dnsop-rfc6598-rfc6303-00 Abstract [RFC6598] specified that: "reverse DNS queries for 100.64/10 MUST NOT be forwarded to the global DNS infrastructure". This document formally requests that IANA add the associated zones to the "Locally-Served DNS Zones" to prevent such queries accidently leaking to the global DNS infrastructure.

Introduction This is a formal request to add the reverse zones for the address space allocated in RFC6598 to the "IPv4 Locally-Served DNS Zone" registry estabilished by [RFC6303]. 2. Changes to Locally-Served DNS Zones To add the following zone listed in RFC6598 Zones (Section 2.1) to the "IPv4 Locally-Served DNS Zone" registry. 2.1. RFC6598 Zones 64.100.IN-ADDR.ARPA 65.100.IN-ADDR.ARPA 66.100.IN-ADDR.ARPA 67.100.IN-ADDR.ARPA 68.100.IN-ADDR.ARPA 69.100.IN-ADDR.ARPA 70.100.IN-ADDR.ARPA 71.100.IN-ADDR.ARPA 72.100.IN-ADDR.ARPA 73.100.IN-ADDR.ARPA 74.100.IN-ADDR.ARPA 75.100.IN-ADDR.ARPA 76.100.IN-ADDR.ARPA 77.100.IN-ADDR.ARPA 78.100.IN-ADDR.ARPA 79.100.IN-ADDR.ARPA 80.100.IN-ADDR.ARPA 81.100.IN-ADDR.ARPA 82.100.IN-ADDR.ARPA 83.100.IN-ADDR.ARPA 84.100.IN-ADDR.ARPA 85.100.IN-ADDR.ARPA 86.100.IN-ADDR.ARPA 87.100.IN-ADDR.ARPA 88.100.IN-ADDR.ARPA 89.100.IN-ADDR.ARPA 90.100.IN-ADDR.ARPA 91.100.IN-ADDR.ARPA 92.100.IN-ADDR.ARPA 93.100.IN-ADDR.ARPA 94.100.IN-ADDR.ARPA 95.100.IN-ADDR.ARPA Andrews Expires April 8, 2013 [Page 3] Internet-Draft Locally-Served DNS Zones Additions October 2012 96.100.IN-ADDR.ARPA 97.100.IN-ADDR.ARPA 98.100.IN-ADDR.ARPA 99.100.IN-ADDR.ARPA 100.100.IN-ADDR.ARPA 101.100.IN-ADDR.ARPA 102.100.IN-ADDR.ARPA 103.100.IN-ADDR.ARPA 104.100.IN-ADDR.ARPA 105.100.IN-ADDR.ARPA 106.100.IN-ADDR.ARPA 107.100.IN-ADDR.ARPA 108.100.IN-ADDR.ARPA 109.100.IN-ADDR.ARPA 110.100.IN-ADDR.ARPA 111.100.IN-ADDR.ARPA 112.100.IN-ADDR.ARPA 113.100.IN-ADDR.ARPA 114.100.IN-ADDR.ARPA 115.100.IN-ADDR.ARPA 116.100.IN-ADDR.ARPA 117.100.IN-ADDR.ARPA 118.100.IN-ADDR.ARPA 119.100.IN-ADDR.ARPA 120.100.IN-ADDR.ARPA 121.100.IN-ADDR.ARPA 122.100.IN-ADDR.ARPA 123.100.IN-ADDR.ARPA 124.100.IN-ADDR.ARPA 125.100.IN-ADDR.ARPA 126.100.IN-ADDR.ARPA 127.100.IN-ADDR.ARPA 3. IANA Considerations This document recommends that IANA the zones listed in RFC6598 Zones to the "IPv4 Locally-Served DNS Zone" registry. 4. Security Considerations As with any other Locally-Served DNS zone, reverse lookups of RFC6598 zones will require non-default configuration to return anything other than NXDOMAIN.
