Re: Comcast is using Sandvine to manage P2P Connections Interesting that in TTL=123 (12.118.177.49) is an ATT Ip Adress. "AT&T WorldNet Services ATT". Isn't Comcast and ATT merged as far as the net? Funchords how did you see that your RST packets had a TTL of 123, i have wireshark installed. |

AT&T Worldnet Services is not the same thing as the old AT&T Broadband Internet. ATTBI was spun off from the AT&T mothership, and became Comcast[1]. But AT&T Worldnet Services was part of the old AT&T, and remained independent of Comcast. In fact, AT&T Worldnet Services was part of the AT&T which was bought by SBC in 2006; and is currently still called AT&T.
[1] Somewhere I got the idea that ATTBI bought Comcast.

Expand the "IP" section (above the TCP section), the TTL appears there. |

If it's not a router, it shouldn't decrement TTL. So TTL=123 includes the non-facing side of the router with a TTL=124, the facing side of the router with a TTL=123, and anything in between.
As a practical matter, it also includes any added technology at either router, such as a Sandvine P2P Policy Management (PPE 8200).
