Allow to request DHCPv6 even when RA does not indicate its use
Description of the feature
I think it might be useful to have only part of network devices to request fixed addresses via DHCPv6. ipv6.method=dhcp
seems currently unusable, because it obtains only local address. But it does not continue to listen for router advertisements to properly configure routing on the host.
I would like to have working routing received from router advertisements, but to skip SLAAC address generation on local host.
Description of the use cases
- I think this would be useful for server machines sharing local network with common clients. We may not make all clients to request addresses via DHCP(v6), because Androids cannot do that anyway.
- But servers should register their hostname and map IPv6 address and its reverse entry into DNS. I do not think we have better way than DHCPv6 at the moment.
- It allows to control IPv6 addresses assigned on single place, dhcp server, which is suitable for all normal servers except routers. I think for servers we usually want shorter addresses than EUI-64.
