I use a Firewalla Gold security router.  It logs and analyses traffic.  I noticed my Merlin RT-AC68U Diagnostic Router is contacting Digital Ocean 208.81.5.45 using UDP 123 'ntp' port.   I have ntp activated in Merlin but it uses pool.ntp.org and time.nist.gov fro ntp.   Any ideas about 208.81.5.45?
