@Brandon

Thank you very very much. That was a great and very quick help. Now to ask the ISP again and see what they will say now.

Regards

Hector

@Andy

Many thanks for taking your time to try that. Still no joy for me. My ISP insist they can do nothing, the problem is outside their reach...

Do this test:

start a command line window (start->execute->cmd)

Enter 'ping www.430oh.com'

you should see  this: "Ping 43oh.com [216.97.227.25]..."
If you see a different IP, the nameserver is returning a wrong IP which likely won't work. If you get an error that it cannto be resolved, then there is no entry for this domain on teh nameserver.
However, It may be that they have a dynamic IP and it will change soon.
In this case, it may be that you onyl get the new IP from your nameserver when it has already changed or changes soon. So most of the time you're getting an outdated IP.

You may try configuring your network connection to use a different nameserver.

Also, some routers act as nameserver proxy. If it has cached a wrong/outdated IP, you might need to reset the router.

Enter 'ping www.430oh.com'

That should be:

ping www.43oh.com

Also try:

ping 43oh.com

The result should be the same

I can confirm that the IP address reported here (at 15:30 BST) is also 216.97.227.25

In theory, you should be able to just enter http://216.97.227.25/ into your browser but, doing that, I just get

Could not determine user from environment

If you try it, and you get the same, then you know that it's a DNS problem...

@Jens-Michael

First of all thank you for your time used to help me. Now I am fighting my ISP (Telefonica del Peru) I think it is their fault. When I ping www.43oh.com I see [216.97.227.25]. All this for 11 (eleven) days now. So trying to know if 43oh is really live. (It is)

I asked 2 of my brothers to do the same. One has DSL connection with other ISP (Claro) and he can connect flawlessly at any time. My second brother can connect without troubles  via his 3G mobile (Claro). The trouble is that in my district I can not get Claro only Telefonica :(

So I consider myself another victim of monopoly, the lack of competence ...

Again, thank you very much

Often, providers (the one of 43oh, not your ISP) put several domains onto the very same IP. Which one you access is determined by some reference information sent with the HTTP request. It is possible that some local privacy options, firewall filtering or using a proxy will make it impossible for the host to determine the domain you're asking for.

@Andy

Tried:

ping www.43oh.com

ping 43oh.com

and ping http://www.43oh.com, here I get [67.215.65.132] and the 4 responses of about 190 ms but clearly it is not 43oh.

Also trying directly  216.97.227.25 in my XP SP 3 with Chrome fails with 

Esta página web no está disponible

Se ha interrumpido la conexión con 216.97.227.25

that translates to about "Web page not available broken connection to 216.97.227.25"

It seems we both wrere writing at same time, so you and I do not read our prior posts.

Thanks a lot for your time and your concern

Hello

I tried to e-mail to webmaster@43oh.com but without luck. Someone knows a way to know the email of 43oh so I can write them directly so they can see what is happening? I guess they can ask the ISP to investigate about this issue

Or any better ideas? I would like to access 43oh web page.

Thank you

Hector

ping http://www.43oh.com, here I get [67.215.65.132]

The 43oh IP is registered to azha.lunarpages.com

However, you shouldn't get a 'boken connection' error when trying the IP. When I try the IP, I get redirected to http://216.97.227.25/cgi-sys/defaultwebpage.cgi which contains the 'cannot determine user form environment' text.

As you did get a ping response, the route to this IP should be okay. Very strange. I suspect a broken HTTP proxy.

What you can try is:

start->cmd->telnet www.43oh.com 80 (or alternatively try the IP)

Enter teh following (you won't see anything):

GET / HTTP/1.1[enter]
Host: www.43oh.com[enter][enter]

This second line is not there when you enter the IP directly (or rather, it contains the IP)

As answer, you should get the entry page of 43oh. Since the telnet client ignores any local proxy settings (but of course may be blocked by a firewall or may be intercepted by a provider proxy), it will work even if there is a problem on your computer (except for a firewall) and fail if there is one on the provider side.

@Jens-Michael

I get "broken connection" with azha.lunarpages.com, the same as with 43oh.

Trying telnet (I have no experience with that) as per your instructions I blindly typed (I think) your two lines with telnet 43oh and telnet 216.97.227.25. I get each time two lines with spaces and a cursor(?) at the end and I think a timeout and returned to the command prompt. No more. Tried that for at least 10 times. I can not get the entry page you mention or something else. I hope I did what you asked to do.

I also tried TRACERT 43oh but I only obtain 30 lines of timeouts. I will read what telnet in XP is trying to do.

Anyway, thanks a lot for your time.

Hector

There is a contact form at http://www.43oh.com/contact-us/ - but I guess that doesn't help you?

Maybe you can contact them via Twitter: http://twitter.com/FourThreeOh

@Andy

Yes, all variations on theme 43oh fail ...

Good info to use twitter.

I wrote the developper of Energia project (MSP430 with IDE like Arduino) and he sent me an email to contact 43oh. I wrote to admin@43oh and few moments ago I received an answer. They say they are not blocking any Ip from Peru and sent me a pdf with the "complaint" from another peruvian in 02/12. Also they sent me his email, so I will write him to ask about his adventures with the same peruvian ISP.

Well, some progress in my winding road ... :)

A lot of thanks for your concern.

Hector

Hello Hector,

A workaround that might be worth trying is to make an entry in your windows hosts file to override your ISP's incorrect DNS information for 43oh.com.  Since most webhosts use shared IP addresses, just entering the IP won't work (as already noted by several posters).  However, after putting in the hosts file entry noted below it will send any requests to www.43oh.com to the proper IP address when you enter www.43oh.com in your browser.  The domain specific information that is required to route the request to 43oh's area of the webserver should be properly transmitted as well. 

You can find the hosts file in XP in this directory:  C:\Windows\System32\drivers\etc

It is a simple text file that can be edited in Notepad and you simply need to add the entry below (without the # symbol in front of the entry):

216.97.227.25      www.43oh.com

Save the hosts file and it will take effect immediately, no need to reboot.

Hope this helps.

 EDIT:  please make sure that you save the hosts file with no extension.  Notepad may, by default, try to save it with a .TXT extension.

 iFORUM (or is it iFORA) is the best humanity invention (more than walking in the moon?). Johannes Gutenberg's invention kill trees and reach less people ... slowly. Also thank you all for sharing knowledge :)

@Dubnet 

Thank for the info and the "trick". I will try that .. erasing the .txt prior to save ;)

Hector

@Dubnet 

To inform you that it does not worked. In the directory you mention there are 5 files, one of them hosts (still without extension) containing the next 2 lines without the # at the beginning of the line

127.0.0.1             localhost
216.97.227.25   www.43oh.com

Also ping www.43oh.com returns 216.97.227.25  and then timeout.

And tracert  returns  216.97.227.25  with

1- <1ms     192.168.1.1

2-  timeout

3- 24ms     10.111.63.13

4 to 30- timeout

Anyway, thank you.

Hector,

Could be a routing problem. Strange that you are seeing a 10.x.x.x IP on the third hop since that is not an internet IP address but is defined as an IANA private IP.  Are you going through another private network prior to the traffic hitting the internet?  When you do a tracert on a website that you can successfully visit, do you see the same 10.111.63.13 IP address as part of the path?  Could be that the 10.111.63.13 address resides at your ISP and a router misconfiguration is sending traffic destined for 216.97.227.25 (and/or the subnet it resides in) into a "black hole" at the ISP. 

Dubnet

Dubnet

What I did beginning at 22:30 my local time (-5 GMT)

ping e2e.ti.com returns 72.233.97.212

ping www.google.com returns 74.125.229.179

ping www.claro.com.pe (Peruvian ISP website that works) returns 201.147.20.245

ping www.telefonica.com.pe (Peruvian ISP website not working MY ISP) returns 200.51.229.135 THEN timeout

And now the tracert ...

Sorry for the lenght of post, but you can get the answer. I live in a quiet small district 25 Km from Metropolitan Lima. Can not get the working ISP the obvious solution. And no private network to my knowledge. Maybe the "solution" from my ISP was "sui generis" adapting a network for us (we are about 7000 people) I do not know how many ADSL connections. I hope you can see something I do not catch (really I am not expert)

Hector

Hi, here another peruvian Launchpad user. I've been having the same problems accessing 43oh. Tracing the domain yield results similar to those shown by Hector, the hops dont go beyond telefonica's own network which suggest some sort of blocking at the ISP level. Other ISPs do not present the same problem.

What I suggest is to use Opera browser on turbo mode, that will tunnel the requests through opera´s servers, outside telefonicas's reach.

Amigos peruanos, usen opera en turbo mode. Es la manera mas facil de entrar a 43oh, que telefonica parece haber bloqueado.

Indeed, that works too.

Tony

Exploring that, looking (googling) at the part "similar web proxies". Effective help so far. Some "troubles" but first time I saw 43oh. Definitely my ISP is not capable to solve the problem :(. I even think they do not realize the problem. :( :(

Thank you very much

43oh does not block any IPs. 

Here is a tip by one of the members. Hope it helps. 

Hello,

Only to say I can see now 43oh. A "sui generis" way, but I can see the site. I say Thank you to all the people here who helped me lot.

I will stop to post in this thread.

Again, thank you all

Hector Segura

Thanks for closing the story.

Glad to hear that you got there in the end!

43oh is offline at the moment. We are having a few host issues.
