NonStop TCP/IPv6 ND6HOSTD Process for DNS
Updates
link-local address, you can communicate between two hosts on the same link
using just those addresses.
NonStop TCP/IPv6 ND6HOSTD Process for DNS Updates
NonStop TCP/IPv6 provides a process called ND6HOSTD that updates the DNS for
IPv6 addresses (provided a DNS server that updates IPv6 addresses exists on the
network). The ND6HOSTD process is managed by the persistence manager. (For
more information, see ND6HOSTD Process on page 2-16 and Managing the
ND6HOSTD Process on page 6-18.)
NonStop TCP/IPv6 Operating Modes
NonStop TCP/IPv6 is implemented as a dual stack, with support for both IPv4 and
IPv6. You can specify these modes for your NonStop TCP/IPv6 environment when you
configure the TCP6MON object:
The default operating mode for the NonStop TCP/IPv6 subsystem is INET.
First specify the SCF FAMILY attribute for the TCP6MON to set the subsystem to
desired mode, then add a SUBNET and specify the FAMILY attribute to set the
SUBNET to the desired mode.

For INET mode,
Add the SUBNET and either specify FAMILY as INET or do not specify
FAMILY at all (INET mode is the default):
->ADD SUBNET $ZZTCP.*.SN1, TYPE ETHERNET, FAMILY INET, &
DEVICENAME LAN02, IPADDRESS 1.2.3.4
->ADD SUBNET $ZZTCP.*.SN2, TYPE ETHERNET, &
DEVICENAME LAN03, IPADDRESS 1.2.3.5

For INET6 mode,
1. Alter the MON to INET6 mode:
->ALTER MON $ZZTCP.*, FAMILY INET6
2. Add the SUBNET and specify FAMILY as INET6:
->ADD SUBNET $ZZTCP.*.SN1, TYPE ETHERNET, FAMILY INET6, &
DEVICENAME LAN02, IPV6RAENABLE ON
