This has been baffling me for some time. A single domain (haxe.org) is inaccessible from my laptop (OSX 10.7.5) while connected via my home network. Attempting to ping it results in "No route to host" and "Host is down" messages.
Thinking it was an issue with my ISP / connection in general, I set up an SSH tunnel to my work to use as a SOCKS proxy. With this in place I can browse the site in chrome and other SOCKS aware applications. Unfortunately this workaround isn't sufficient as the haxelib commandline tool I'm trying to use doesn't do SOCKS. Being the first thing I tried when others told me the site was still up, I assumed this isolated the issue to my Internet connection.
In a stroke of inspiration this morning, I attempted to browse the site using an iPad. Lo and behold, it works! But from the laptop, still nothing. The iPad is connected to the same network (both over wifi), can browse the site with no issue.
My fault is at the same not with my laptop, and not with my network. At this point I fear the solution may be painfully obvious, but after staring at this problem for days I cannot see it.
Any and all suggestions are welcome.
PS: The domain is resolving correctly to 5.39.76.185 regardless of tunnelled vs direct connection. Both the iPad and laptop are set to use my router for DNS and it is set to my ISP's recommended IPs. (Before troubleshooting, it was set to OpenDNS servers)
[UPDATE]
As per user3050461's suggestion, I've included the output of route below. I believe we've found our culprit, but WHY? What's a ham0 interface, and who the heck is monreseau.home ("mynetwork.home" in french)??

[UPDATE 2]
What is ham0 and why is it stealing (is it?) every address that starts with 5 (haxe.org's 5.39.76.185 included)? What is the syntax to delete this from my routing table?
