Restrictions and Features
Restrictions and Features
Restrictions
•
To make DNS a persistent process using the NonStop Kernel Persistence Manager
($ZZKRN), you should have the G06.24 RVU installed on the system.
Features
•
DNS Protocol Enhancements
Incremental Zone Transfer (IXFR), NOTIFY, and dynamic updates are used for
efficient zone transfer, reducing size and duration, and supporting the increasing
amount of data being exchanged between Name Servers.
•
IPv6 Address Resolution
The A6 Resource Record (RR) is used for address translation between a domain
name and an IPv6 address, and can be used to replace the currently used AAAA
RR.
•
The following RFCs are supported:
•
RFC 1886: DNS Extensions to Support IPv6
•
RFC 2874: DNS Extensions to Support IPv6 Address Aggregation and
Renumbering
•
RFC 2845: Secret Key Transaction Authentication for DNS (TSIG)
Assumptions and Dependencies
•
Applications running in either OSS or Guardian can access the Name Server but
the named process must run in OSS.
•
For the Name Server to listen to IPv6 addresses, NonStop TCP/IPv6 must be
running in DUAL or INET6 mode (refer to the TCP/IPv6 Configuration and
Management Manual in NTL for more information).
•
$ZZKRN is used to make DNS 9.2.3 run as a persistent process.
Tools
The following tools are supported as part of the DNS 9.2.3 product (for more
information about a tool, refer to the BIND 9 Administrator Reference Manual in NTL).
named-bootconf
The named-bootconf tool is a shell script that converts a DNS 4.8.3 configuration file
to a DNS 9.2.3 configuration file.
