Here is the response of running traceroute to a router at my workplace, notice the loop it was in starting at hop 13. I set the ttl up higher and let it run, finally killed it at 75 hops, stuck in that loop. Any idea what this loop means? Is it something I should be concerned about? (I think probably so, but what to do about it?) 1 firewall (192.168.1.10) 0.548 ms 0.495 ms 0.437 ms 2 pia152-1.pioneernet.net (66.114.152.1) 25.289 ms 25.510 ms 24.918 ms 3 sea-gw.isomedia.com (207.115.64.129) 25.236 ms 26.040 ms 25.323 ms 4 isomedia-gw.peer1.net (216.187.64.97) 25.712 ms 25.601 ms 25.234 ms 5 500.serial1-11.gw7.sea1.alter.net (157.130.191.5) 25.957 ms 27.009 ms 25.193 ms 6 146.atm2-0.xr2.sea1.alter.net (152.63.105.182) 25.536 ms 26.145 ms 26.213 ms 7 0.so-0-0-0.xl2.sea1.alter.net (152.63.106.233) 26.180 ms 25.738 ms 26.366 ms 8 0.so-0-1-0.tl2.por3.alter.net (152.63.107.157) 30.913 ms 32.464 ms 30.998 ms 9 0.so-3-0-0.tl2.lax9.alter.net (152.63.0.166) 55.209 ms 53.563 ms 53.028 ms 10 so-1-0-0.xl2.lax2.alter.net (152.63.3.186) 55.045 ms 54.098 ms 53.750 ms 11 pos4-0.xr2.lax2.alter.net (152.63.115.230) 54.213 ms 53.845 ms 54.252 ms 12 194.atm6-0.gw3.lax2.alter.net (152.63.53.53) 54.191 ms 60.878 ms 54.468 ms 13 63.66.44.161 (63.66.44.161) 94.501 ms 101.446 ms 94.261 ms 14 loopback0.gw3.lax2.alter.net (137.39.4.239) 92.190 ms 92.471 ms 93.983 ms 15 63.66.44.161 (63.66.44.161) 132.684 ms 134.368 ms 132.027 ms 16 loopback0.gw3.lax2.alter.net (137.39.4.239) 130.411 ms 131.085 ms 131.765 ms 17 63.66.44.161 (63.66.44.161) 172.050 ms 171.177 ms 171.734 ms 18 loopback0.gw3.lax2.alter.net (137.39.4.239) 169.930 ms 169.775 ms 170.520 ms 19 63.66.44.161 (63.66.44.161) 210.168 ms 210.279 ms 210.418 ms 20 loopback0.gw3.lax2.alter.net (137.39.4.239) 212.299 ms 210.743 ms 222.284 ms 21 63.66.44.161 (63.66.44.161) 248.152 ms 249.663 ms 248.181 ms 22 loopback0.gw3.lax2.alter.net (137.39.4.239) 244.978 ms 245.228 ms 244.663 ms 23 63.66.44.161 (63.66.44.161) 286.913 ms 286.252 ms 287.396 ms 24 loopback0.gw3.lax2.alter.net (137.39.4.239) 283.819 ms 283.658 ms 283.639 ms 25 63.66.44.161 (63.66.44.161) 324.938 ms 323.692 ms 326.406 ms 26 loopback0.gw3.lax2.alter.net (137.39.4.239) 321.902 ms 321.866 ms 330.534 ms 27 63.66.44.161 (63.66.44.161) 361.828 ms 362.492 ms 369.959 ms 28 loopback0.gw3.lax2.alter.net (137.39.4.239) 360.428 ms 373.390 ms 368.992 ms 29 63.66.44.161 (63.66.44.161) 399.827 ms 400.560 ms 399.828 ms 30 loopback0.gw3.lax2.alter.net (137.39.4.239) 399.692 ms 398.802 ms 398.611 ms TIA -- Chip W.
