Hi Assed,
If BlueZ hasn't introduced a mechanism of its own recently, there is no
dedicated BueZ IP address assignment mechanism. Of course, you may use
DHCP if a suitable server is available.
The Bluetooth PAN specification ("Personal Area Networking Profile
v1.0") recommends the "Zero Configuration Networking (Zeroconf)"
standard (http://www.zeroconf.org/) with
draft-ietf-zeroconf-ipv4-linklocal-02.txt (or actually one of its
successors) as instant ("zero configuration") IP address assignment
algorithm. The code for UNIX (called 'zcip') used to be available at
http://zeroconf.sourceforge.net/?selected=zcip, but currently there seem
to be intellectual property problems with it (see explanation on web
page), so that the code has been removed. Actually it creates an IP
address out of the 169.254/16 address range with a mathematical
transform that is seeded by the network adapter's MAC address. It
queries for potential collisions via AR, and defends an assigned IP
address against subsequent collisions via ARP.
Hope this helps,
Michael
