remove ipv6 addresses router mac os network settings

I hope this helps but please ask further!ġ) you have already found the biggest drawback of staless autoconfiguration: lack of DNS information. The EUI-64 derived IPv6 address 'speaks only when spoken to'. However, for outgoing connections, these operating systems will use the pseudo-random address. These operating systems will respond if they are contacted on every their IPv6 address.

With operating systems supporting the IPv6 Privacy Extensions, they also create a pseudo-random suffix to the IPv6 prefix received in the Router Advertisement message, and so, they have two global unique addresses - the one with the 64 random bits in the host part, and the one using the modified EUI-64. It will then use this globally unique address. The host simply uses this EUI-64 concatenated with the prefix received in the Router Advertisement and form a globally unique address. Thus, the need for DHCPv6 is by far not alleviated and I am certain it will never be because the autoconfiguration is just a 'quick-and-simple' way of doing things while the DHCPv6 is the fully-fledged solution for centralized IPv6 settings management (think of having fixed IPv6/MAC bindings, automatic web proxy discovery, TFTP service for IP phones, wireless LAN controller address for lightweight access points, WINS, whatever else is out there that can already be pushed to client via DHCP - the stateless autoconfig simply is not meant to provide these settings).Ģ) I do not entirely understand your question but generally, if a host receives a Router Advertisement message, it already has its own link-local address (derived from its MAC address as a modified EUI-64). The stateless autoconfiguration in IPv6 provides some of the most important IPv6 settings but it is not readily extensible and as an example, as you pointed out very correctly, the DNS server address cannot be currently assigned via Router Advertisement messages.
