You may want to fix that IP address and/or netmask...

Did this cause a real problem at your site or just some "monitoring noise"?
Is it still an issue? I suppose it was a temporary glitch somewhere:
$ host cvmfs02.grid.sinica.edu.tw
cvmfs02.grid.sinica.edu.tw is an alias for host-117-103-109-217.twgrid.org.
host-117-103-109-217.twgrid.org has address 117.103.109.217
