Okay thank you I've been so confused with all this that it didn't even occur
to me - its now responding as expected - but I still have my original TCP

the entire session is perfect...

Anyone at all? Any suggestions on further tests?

Thanks again

try ping -nR -c1 x.y.186.254

If you don't get the same "lag" then it is your DNS lookup that is
causing the problem.
