Re: pings

The pings you are seeing from pnap.net probably resolve to performance
or fcp boxes that they use to help map out paths from thier "PNAP" to
your network.  They then take these performance metrics and decide
which exit point of the pnap gives the best performance and route
accordingly.  I wouldn't be concerned with these.
