Yes. > Like I said before, that would pollute the network with many multicasts which > can seriously degrade wifi performance. Huh? This is no worse than IPv4 where a host comes up and sends a subnet-broadcast to get DHCP. I have never heard of a network brought to its knees from these requests. A single packet each time a host boots is hardly a high PPS rate. > And networks without RAs are very common. We call those networks "IPv4-only > networks". No, we call those server networks. I've seen lots of IPv6 networks with RA's disabled and all static devices on them. Sometimes having hosts dynamically get addresses and default routes is a bad thing. > And in the current situation DHCPv6 without router advertisements is > pointless because you may get an address, but you have no place to send your > packets. Which is what we would like to fix. -- Leo Bicknell - bickn...@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/
