forwarding them as needed. IPv6 tunneling eases IPv6 deployment
by maintaining compatibility with the large existing base of IPv4
hosts and routers.
• Full Ethernet Link Support.
• IPv6 Stateless Address Autoconfiguration.
• IPv6 Neighbor Discovery (which includes Router Discovery and
Duplicate Address Detection).
• TCP/UDP over IPv6, PMTUv6, ICMPv6, IPv6 MIBs and Sockets
APIs.
• Network Configuration and Troubleshooting Utilities for both IPv4
and IPv6: ifconfig, netstat, ping, route, ndd, ndp
(neighbor-discovery command for IPv6 only) and traceroute.
There have also been enhancements to nettl and netfmt for IPv6
tracing and formatting.
• New netconf-ipv6 file stores IPv6 settings. The
/etc/rc.config.d/netconf-ipv6 configuration file stores IPv6
configuration information similar to IPv4’s
/etc/rc.config.d/netconf file.
• The /etc/hosts file now supports IPv4 and IPv6 addresses. The
/etc/hosts file contains IP addresses and corresponding host
names. The file can contain IPv4 and IPv6 addresses for the same
host. Lookup policies are identical to IPv4.
• Name Service Switch: /etc/nsswitch.conf is a configuration file
for the name service switch. A new entity, ipnodes, specifies which
name services resolve IPv6 addresses and host names. Refer to the
nsswitch.conf(4) man page for more information.
IMPORTANT If you have an /etc/nsswitch.conf file, and if you have set a hosts
entry in that file, then you must set a similar ipnodes entry. You
must do this even if you do not use IPv6 addresses. Also, be aware
that you cannot use NIS or NIS+ on the ipnodes entry.
• The following IPv6-capable Internet Services are included with
HP-UX 11i IPv6 bundled as part of TOUR 1.0:
— inetd, Internet Daemon
