Caution:
By the nature of the EDNS0 protocol, Cisco Prime Network Registrar 8.3 DNS servers interoperate with earlier
versions of Cisco Prime Network Registrar DNS (and third party DNS vendors). EDNS0 defines the interoperability
with DNS servers that do not support EDNS0. Cisco Prime Network Registrar 8.3 DNS adheres to the RFC and
consequently interoperates with earlier versions of Cisco Prime Network Registrar.

New Features and Enhancements
This section describes the features added in Cisco Prime Network Registrar 8.3.
Client-based DNS64 Prefixes
Cisco Prime Network Registrar DNS caching server supports DNS64, synthesizing AAAA (IPv6) records from A (IPv4)
records, when an IPv6 client queries for AAAA records. DNS64 also handles reverse queries for the NAT64 prefixes.
DNS64 with NAT64 provides access to the IPv4 internet and servers for hosts that have only IPv6 addresses. Cisco Prime
Network Registrar 8.3, now supports up to 30 IPv6 prefixes in synthesis of IPv6 address for IPv4-only server instead of
single prefix. The requests are matched to DNS64 prefixes using ACLs.
