Sorry, I found out what caused it now.  Its not a routing problem or
anything, just needs some tweaking.

If of any interests:
It was caused by programs asking for the ipv6 ip (AAAA) when the host only
had ipv4 ip(A). I guess we will be seeing more of that in the future :-)
The nameserver converted the ipv6 request into an ipv6 ip, when it really
was ipv4 (so thats why it went into 54fx:: -range).
Our ns converts A/AAAA requests into ips in a predefined radix. The
nameserver is zoneless and uses the actual host instead (great for /64
routeradvertised netblocks).
