Why am I not getting anything back when I 'ping' certain
domains?  Episode 922 (1:15:48)  Adam from Hesperia, CA
'Pinging' is a method of directly contacting a site just to
confirm there's a connection there. According to the chatroom,
if he has too many devices on his FiOS router, it could be
preventing the router from connecting temporarily. Each device
takes up an entry on the NAT table (Network Address
Translation). Size limitations on that NAT table could cause the
router to choke.
