Looking at this test, there is no need to use IP4|6_NETWORK vars
and *_L|RHOST_. We could just use "unused network" variables there.
I'll prepare the patch... but still we need to get a reverse net,
though these variables more or less static.

If we want to automate it, may be create reverse IP program as
a separate tool in LTP so it can be invoked inside tests, like
dns-stress?

Thanks,
