D-STAR DD (Ethernet over D-STAR) Identifies in D-STAR frame, which
encapsulates the Ethernet packet, which incapsulates the IP packet.
AX.25 Identifies at the AX.25 frame level.
HSMM uses ICMP or other methods to identify in the clear (
http://en.wikipedia.org/wiki/High-speed_multimedia_radio#Identification)
In the US a transmitter must identify every 10 minutes during a
'communication' and at the end of a 'communication'
The network should not enforce the most restrictive country's rules -- that
is the obligation of the control operators of transmitters in that country.
DNS and reverse DNS should map the FQDN of the station along with its IP
address. There are provisions in the TOS to delete allocations if it is
abused.

Not that I am aware of. The IP traffic has NEVER required any callsign
identification. Nor has the TCP traffic. Transmissions over the air are
always carried atop layer 2, which is the AX.25 Link Layer protocol. The
transmitters on each end of every radio link use the callsign to identify
each and every frame sent over the air. Our callsigns are used in AX.25
Link Layer in the same way that MAC addresses are used in the 802.3
ethernet layer 2 / link layer protocol. Take a look at your ARP table to
confirm this.
The "transmitters" must be identified, and they may identify *within*
the published protocol (in this case AX.25). This is all that the FCC
requires.
