DHCP 4.2 seems to have a hack to dig into DUID-LLT and DUID-LL to pretend it is keying off of mac (for multi-homed systems, it will still behave in a wonky way, and NIC replacement behaves a lot differently, and you have the chance of duplicate matches if you swap nics and reinstall one). If you have a lot of control over your provisioning strategy, I have some options I could exercise for a more robust strategy. </span><br>

Hi,<br>I have some trouble with dhcpv6. I have installed version 4.1.1<br><br>1. DHCPv6 no longer uses mac addresses for fixed ipv6 addresses, instead it need DUIDs (14 bytes). I tried for my Vista computer DUID and succeeded.<br>
a) How can I view DUID for Linux and XP computers, I couldn't find in regedit?<br> b) where is the DUID stored, will it change when the operating system disk formatted-reinstalled? It's a big problem for my cooperate database.<br>
<br>2. DHCPv6 doesn't supply router address for clients, instead it supports prefixes. I tested it with no-RA environment; but the clients couldn't find the gateway; so RA is mandatory.<br> Sometimes RA may be undesirable; is there a thought to change IPv6 RFC and ISC-dhcp in future, for router address assigning?<br>
<br>Thanks in advance<br><br>Tugrul<br>
