Actually AboveNet seems to peer with Comcast:
5. xe-1-1-0.er2.iad10.above.net =
0.0% 53 5.8 6.4 5.7 31.9 3.7
6. above-comcast.iad10.us.above.net =
0.0% 53 6.4 6.4 6.1 6.7 0.1
7. pos-3-12-0-0-cr01.ashburn.va.ibone.comcast.net =
0.0% 53 6.3 6.4 6.2 6.6 0.1
But Cablevision in New York is in fact another example of this problem:
4. dstswr1-ge3-12.rh.nyk4ny.cv.net =
0.0% 78 17.8 41.2 15.0 242.9 33.5
5. 64.15.5.142 =
0.0% 78 44.6 42.9 23.9 82.5 9.0
6. ???
7. ???
8. pos-3-12-0-0-cr01.ashburn.va.ibone.comcast.net =
2.6% 78 267.2 500.6 44.6 703.6 182.9
9. 68.86.91.166 =
2.6% 78 273.9 500.0 46.5 701.9 183.9
