I am using Comcast Cable Internet. Suddenly I cannot ping my home pc. When using tracert:
14 6 ms 6 ms 6 ms 12.125.33.34 15 6 ms 6 ms 6 ms bar02-p7-0.ndhmhe1.ma.attbb.net [24.91.0.46] 16 7 ms 6 ms 7 ms c-24-218-191-206.ne.client2.attbi.com [24.218.191.206] 17 7 ms 7 ms 7 ms 24.218.190.66 18 7 ms 7 ms 7 ms 24.218.190.118 19 * * * Request timed out. 20 * * * Request timed out. 21 * * * Request timed out.
Seems it stopped at 24.218.190.118. And when using tracert on my home pc, the first hop is 10.84.xxx.xxx.
Did Comcast implemented something to block the inbound connection for the cable internet subscript?
