New for the HP-UX 11i v2 Release
The HP-UX 11i v2 release has the following transport (IP, TCP, and UDP) changes:
• Transport support for IPv6
IPv6 is the next generation Internet Protocol. IPv6 requires support from hosts and
routers. HP-UX 11i v2 IPv6 transport software provides host support for IPv6.
With only a few configuration steps, an IPv6 interface can be enabled, and you can use the
functional features of IPv6 and IPv6-enhanced components for HP-UX 11i v2.
NOTE The following software currently offers IPv6 support: Transport, Internet
Services, DCE, DLPI, FDDI, SAM-NNC, Libc, Commands, Desktop (CDE),
X11R6-based applications, EMS, Online Diagnostics, SNMP, nettl, IPSec,
Kerberos Client, Service Guard, Glance, HP-UX Secure Shell, Apache and
JVM. Refer to product-specific documentation for more information.
If you are not planning to use IPv6 software, there is no impact to you. Even though the
software is included, other than a few new files and man pages, there are no actions
required to “not use” IPv6.
To learn more about IPv6 transport on HP-UX 11i v2, refer to the following
documentation, all available at:http://docs.hp.com/hpux/netcom/index.html#IPv6

NOTE This Guide only covers IPv4 related transport information. It does not cover
IPv6 related transport information.
• Transport Support for HP-UX 11i v2 DLPI enhancements
An OOP (Options negotiations and Out-of-Packet) header has been added to the front of all
IP packets for both inbound packets from DLPI layer and outbound packets to DLPI layer.
This change supports the HP-UX 11i v2 DLPI enhancements to the Streams Interface to
provide a richer feature set for network stack feature options.
