mentioned, it's mandatory in IPv6, even for the MAC based addresses. Also, when I was watching with Wireshark, I didn't see and DAD by the DHCP server (pfSense). I'm certainly no expert, but I'm pretty certain the DHCP server (isc dhcp) does it, but I would have to check.
It's easy enough to check the DHCP server. Just fire up Wireshark and filter on arp. If you see arps for the new address from the server, then it does. However, relying on DHCP for DAD doesn't help with static addresses. The idea is that as a device connects to a network, it checks for the assigned address, no matter how it was assigned. Some of us here may recall the days before DHCP became popular and the issues of keeping track of addresses, to prevent conflict. Many years ago, I worked at IBM Canada headquarters, where there were about 4000 employees and static addresses were used. Back then I had 5 static IP addresses, one for my computer and 4 for testing in my work. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
