This is something that has been bugging me for a while now. I'm completely unable to reach http://www.irisindigo.com/ from my home network. From my work machine I can reach it just fine though. I've been wondering if the site admin has me on some sort of block list on his firewall.

This is what my traceroute shows:

Sorry about removing the first few hops, in both of the trace routes, but it definately looks like your failing on the last hop, It could be a firewall, but I don't know why you would be blocked, do you have access to any other IP addresses in your range?

and have you tried contacting the owner(s) of irisindigo to see why?

Hmmhh... In the whois database there are two nameservers listed for his entry: ns1.fujisawa.com (207.152.97.1) and ns2.fujisawa.com (209.251.103.253). In another entry of the company (http://www.fujisawa.com), for which he is probably working for, are the same nameservers listed, but ns2.fujisawa.com as another IP: 207.152.97.2 - :roll:

Stranger still that his internet provider is the same as mine (speakeasy.net)! I bet he set up some sort of rule on the 64.81.*.* range that is preventing me from reaching him.

I just sent the webmaster an e-mail from my work account to see if this was intentional or a configuration issue. Thanks for all the feedback!

Ah, so I'm not alone! Well I e-mailed him from my work account Friday; I won't be able to check for a response until tomorrow morning (Monday).

I noticed he visited Nekochan Net afterward so I'm pretty sure he got it :) Still can't reach the site as of today.

Add me to that list of people who can't get there...
I stop after
12 spk-1-chi.dsl-isp.net (64.94.35.193) 71.350 ms 68.251 ms 78.321 ms

I'm wondering does he have the whole 64.*.*.* blocked? (I'm also on that block, but I'm 64.171.124...)

Oh, and from another machine I have access to (on a 64.71.... block) is also dying at that same host...

Are we sure this site isn't down and whatever you're getting to from work isn't some work-imposed proxy cache or something?

----update----
I just did a traceroute from my work's server (which is NOT a 64.x.x.x ip) and it CAN in fact get to that ip via traceroute, so ya, looks like he has 64.0.0.0/8 blocked?

Yeah ... the main reason I wanted to be able to visit that site is because of the forum on there.

Not a big thing I guess, this one's pretty good ;)

64.0.0.0 is (if I recall my 'proper network classing'), a class A subnet, so it could even be some sort of routing issue on behalf of Speakeasy. If they took that class A and split it into several subnets (say, one for every major region or whatever), and didn't configure that chi router properly...it might just be trying to deliver the return packets locally instead of forwarding to a different subnet of the 64/8 block...

Unfortunately, since we grew a real network group here a couple years ago, my routing skills have gotten hella rusty, and I'm not on speakeasy anyway, so I can't really test...<shrug>

Or, I might just be really, really wrong. :P

Well now that I've had this problem on my own site I know of a likely cause - an improper netmask.

IRIX by default sets the netmask to 0xff000000 so if your server's IP happens to be in 64.0.0.0 will effectively block 64.0.0.0/8. I'd forgotten to uncheck the default box and set my netmask to 0xffffff00. I'm guessing the admin of irisindigo.com has done something similar.
