This is exactly the plan. The /56 is parceled into /64s for each invididual vserver gust. There's a problem, however. My hoster won't (can't) give me more than a /56 for each rack. I need at least two /56 however (one IPv4 /32 for each IPv6 /64). It just occured to me that I can set up a local 6to4 relay router http://wiki.debian.org/DebianIPv6 and produce private IPv6 space for each public IPv4 /32. Are there problems associated with this, or can I go ahead with it? > And the whole /56 should also be terminated in a null route by doing > something like > > ip route add unreachable 2a01:4f8:7d:300::/56 > > or you may cause a routing loop which can be used to DoS your upstream > link. I don't understand that remark yet, as I'm pretty new to IPv6 and networking in general. -- Eugen* Leitl <a href="http://leitl.org">leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
