On an IPv4 network, I am used to being able to track devices by ip address (copyright violation, spam complaints etc.). Static addresses are in the DNS and DHCP config, while dynamically assigned addresses e.g. visitor's laptops appear in DHCP logs or access controller logs.
The Freenet6 tunnel in router mode spawns radvd and devices use IPv6 neighbor discovery to auto-assign addresses. On my Fedora Core 9 system I cannot see anything logged by radvd,
although the manpage says the default is to log to syslog. If I try setting debug level 4, I still
don't see any log of what ip address is assigned to what MAC address.
(Windows Vista assigns radically different IPV6 addresses to the same NIC on the same PC)
So I was wondering:
- is there a way to log assigned addresses from radvd ?
- is DHCP6 a preferred way to go ?
- is there a reliable way to find what's on the network ?
