I'm having trouble connecting to a particular website. I can view it through a proxy, but not from home. So I ran a traceroute:

Tracing route to []
over a maximum of 30 hops:

  1    <1 ms    <1 ms    <1 ms  <snip>
  2     *        *        *     Request timed out.
  3     9 ms     7 ms    27 ms []
  4     8 ms     7 ms     7 ms []
  5    10 ms     9 ms     9 ms []
  6    27 ms    23 ms    22 ms []
  7    18 ms    18 ms    20 ms []
  8     9 ms    11 ms    10 ms
  9     *        *        *     Request timed out.
 10     *        *        *     Request timed out.

Looks like this "" is somehow blocking me. Can I tell my computer to avoid/bypass that IP when trying to connect?

Great question! Seems impossible to me, because you have no control over the route your packets will get, but I'm not sure. – axk Apr 29 '10 at 20:06

For one, I can load the site fine. See the route:

It would appear that (somehow) the two nodes, 9 & 10 in my route, are either blocking ICMP packets or have some other form of network voodoo implemented. It could be that when you were accessing the site through the proxy, you were accessing some cached version when the website was really down, who knows. The fact that there is 100% packet loss in nodes 9 & 10 is odd, but since I can (obviously) reach the site, it doesn't appear that (Peer1 Internet Bandwidth & Server Co-Location Facilities, 2155-500 West Hastings St., Vancouver) is doing anything to block any traffic (in all likelihood, they are just ignoring ICMP packets).

To more directly answer your question, it's pretty much impossible to define your own route to a site. Since (I would assume) all packets would pass through that address at one point or another to get to the actual host (as it's the external IP of the datacentre the servers are hosted in), there would be no route around it. Once your packet gets outside of your router, it's up to Shaw what route your packet takes; you have no control whatsoever. Hope that helps a bit!

ICMP packets == pings? It's not just that. When I try visiting the site in my browser, it tries loading for a couple minutes and then gives me "The connection was reset". And it only seems to be me that that's having this problem, even after I moved several blocks. But I could view it from my school... and my friends can view it, and they're relatively nearby... must be related to Shaw? – mpen May 4 '10 at 7:11
He can try a VPN, that could go through a different route. – Keltari Jan 24 at 23:25

I think you can do this by forcing a particular IP routing using the route add command at the command prompt, but it will take a better man than I am to explain exactly how. You might do a search on 'add a static IP route' or 'force IP routing' to get some idea. I don't know if you can block a specific node, but I wouldn't be surprised if you can. Forcing a specific route that avoids the node would be the alternative.

The only problem is you have no control over what route your packet takes once it leaves your premises. The massive routers of the Internet will just follow their BGP tables and send the packet on whatever route they feel is best. – squircle Apr 29 '10 at 20:46

Are you going to a site that is somehow geographically restricted? There are sites that will only accept traffic from certain regions and if your IP address is not within their allowed list, the packets may be eaten. The reason I'm asking is that you said you can access through a proxy.

No. In fact, I made the site myself. Years ago. Before I had this problem :\ – mpen May 4 '10 at 7:05

Well if you actually track the ip geo-location using you can see that its not just automated nodes but it is big brother and other countries that are spying on you using your router as a hub.

Get the geo-location of the ip and you will see that I am correct. Trust me its not just automated nodes and such a good %90 of the time its a government organization stealing your information.

I have done trace routes from my cpu to my same cpu and pulled up 30 ip addresses.

Have fun.
