8 Networking Products
The G06.25 RVU contains new features for these networking products:
•
Domain Name System (DNS) 9.2.3
•
SNAX/APN
Domain Name System (DNS) 9.2.3
The latest version of BIND (9.2.3) is now available on NonStop servers, including these
new features:
•
DNS protocol enhancements, including Incremental Zone Transfer (IXFR),
NOTIFY, and dynamic updates for efficient zone transfer to support the increasing
amount of data being exchanged between Name Servers.
•
IPv6 address resolution enhancement whereby 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.
•
Alternate resolv.conf files, which you can specify through either the shell prompt or
an application.
•
A run-time option, which you can use to specify an alternate TCP/IP process for
use by the named process.
•
These enhancements are supported:
°
DNS extensions to support IPv6
°
DNS extensions to support IPv6 address aggregation and renumbering
°
Secret key transaction authentication for DNS (TSIG)
The version of DNS 9.2.3 available with this RVU does not support secure DNS.
Migration
•
DNS 9.2.3 supports all the enhancements developed for the older BIND 4.8.3
version of DNS with no regression or limitations.
•
DNS 9.2.3 works with all currently supported TCP/IP products such as
Conventional TCP/IP, NonStop TCP/IPv6, and Parallel Library TCP/IP.
•
If the network is a pure IPv4 network, only one instance of the Name Server is
needed, and it is necessary to support X.25, Token Ring, or Asynchronous
Transfer Mode (ATM) protocols, the Conventional TCP/IP product should be used.
•
If the network is a pure IPv4 network, and multiple instances of the Name Server
are needed on the same system, use the NonStop TCP/IPv6 in IPv4 mode or
Parallel Library TCP/IP products.
•
If the network supports both IPv4 and IPv6 environments, use the NonStop
TCP/IPv6 product configured in dual mode.
