For those DST ip addresses I've got failures
Which kernel is this test running on? That message
is gone since 2.6.22.
s3p@burnin:~$ uname -a
Linux burnin 2.6.22-14-generic #1 SMP Sun Oct 14 23:05:12 GMT 2007 i686 GNU/Linux

This was the config where I detected the problem. (Ubuntu 7.10)

I didn't find the reason why your kernel even has that message
(didn't try to hard though). Could you rerun the test with a
more current kernel, like 2.6.24 or 2.6.25 please?
