Hello everyone, Site-local IPv6 addresses (fec0::/10) have been deprecated by the IETF. A while ago, on this very mailing list, Jeroen pointed out that a better approach was to use Unique Local Addresses (ULA). The Internet draft for these has been IESG-approved. My site has a non permanent Internet connection with a dynamically assigned IPv6 /48 prefix. So I need some kind of private prefix both so that I can use the local network while the Internet connection is down, and also to put permanent addresses in the local DNS. I've been trying to use ULAs, but it seems that the Linux kernel breaks (and I suspect Microsoft's too) when it has both ULAs and global public IPv6 addresses. Hosts seem to try to use their ULA addresses to reach the external IPv6 Internet, when the router advertises both public and private IPv6 prefixes. That makes it impossible to reach any external IPv6 node :( Has anyone had any success with ULAs or has another solution? -- Rémi Denis-Courmont http://www.simphalempin.com/home/
