Address Assignment and Auto Configuration
The snom m9 is IPv6-ready so it can automatically assign an IPv6 address to the device over DHCPv6, and
when connected to an IPv6 network, it can configure itself automatically using Internet Control Message Pro-
tocol version 6 (ICMPv6) router discovery messages. The Dual IP Stack allows the snom m9 to maintain IPv4
and IPv6 interfaces in parallel.
Dual IP Stack
The ability to perform DHCPv6/ICMPv6 queries simultaneously with the IPv4 DHCP queries allows the snom
m9 to maintain multiple IPv4 and IPv6 interfaces in parallel.
128-bit addresses instead of the 32-bit addresses of IPv4
Transmission of a packet to multiple destinations as part of the base
specification
Neighbor Discovery and address auto configuration allow hosts to
operate in any location without any special support (PnP)
Security features are mandated in IPv6 (IPSEC)
No triangle routing—IP mobility is native to IPv6
Efficient and extensible IP datagram
