When I run ethereal from my Wndows XP computer on home network (I have a
netgear router that provides DHCP and DNS services), I see a broadcast
packet every 2.5 seconds from source ximetaTe_18:02:a2 using protocol
0x88ad. I have googled this, but have not found anything. Could some one
please tell me what this is?
Perhaps somebody from Ximeta (or XiMeta, or XIMETA, or however they
capitalize it) can.
The IEEE list of registered Ethernet types at
http://standards.ieee.org/regauth/ethertype/eth.txt
says 88AD is assigned to XiMeta Technology Americas Inc., with the comment
We are manufacturing a series of devices
that are connected to the Ethernet requiring
secure data transmission. Because of the
security reasons, the communication between
the devices is done through a proprietary
communication protocol instead of well known
protocols such as IP. We therefore need
an Ethertype Field for the Ethernet frame
to embed our proprietary communication protocol.
The "proprietary" part suggests that some of the security might be
security-through-obscurity - "we're secure because we don't use that
insecure TCP/IP!", as suggested by their page at
http://www.ximeta.com/technology/ndas/index.php
so perhaps they won't tell you what it is, however.
Do you have one of their devices?

If so, it's probably sending out packets looking for a server, or
something such as that.
