I administer a server remotely, and just moved a domain name from one I.P. address to another. One of my machines is having no trouble accessing the site at the new location, while the other is returning 404 errors. The one returning the error even pings to the old I.P. address, while the one working pings to the proper address.

The wierd thing is that both machines are on the same cable modem. Is there some kind of cache that is not being cleared in the one machine, causing it to keep going to the old I.P. address?

Are they both using the same name servers?

NeXTLoop · Feb 15, 2003, 04:59 PM

They're both using the same ISP... so yes they should be.

Also, I don't have them connected via a router. I've just got an ethernet hub to allow them to both access the cable modem.

Have you entered something in Name Servers in the Network Preference Pane?

NeXTLoop · Feb 15, 2003, 05:18 PM

Nope. Our I.P. addresses are assigned automatically, but our ISP doesn't require any nameservers to be entered. So I'm assuming they're using the same ones, but not certain.

Also, I just noticed that each machine is using a different router from the ISP.

Does this sound like a problem with this particular machine, or something with our ISP's settings?

BTW, thanks for the input.

Perhaps they're using different name servers too.

How long was the time to live on the domain?

Ok, things just got wierder. I went to put the machine, an iBook, to sleep. In the past, that has sometimes helped quirky network problems. When I put the machine I sleep, for a minute I thought I had accidentally hit "Shutdown." Everything went dead, but there was no sleeping light indicator flashing. When I tried waking it, trying the mouse, keyboard and power button, nothing happened. The only way I knew it was on was that the plugged in FireWire HD was still getting power. I ended up having to hard restart by holding down the power button.

But even after rebooting its still going to the wrong address. So at this point, I'm beginning to think it has to do with my ISP. I called them and they think the router my machine is accessing thru may be having problems refreshing. Course now I've got the sleep issue.

Thanks for the help though.

Well, this is starting to get annoying. After almost 24 hours, my computer is still pinging the wrong I.P. address. I've restarted multiple times, I've even traded I.P. addresses with the computer that is accessing it properly. When I did that, my machine couldn't even connect to the Internet.

My ISP doesn't really think its them, and I'm beginning to agree with them, although I certainly hope I'm wrong.

What's the domain and the old and new IPs

NeXTLoop · Feb 16, 2003, 04:29 PM

The domain name is www.eliteinteractive.com. The I.P. address used to be 66.223.21.80. The new address is 66.223.21.81. I've had a few friends that use a different ISP all look at it, and they have no problem. Like I said, even the computer in the same office, using the same ISP and cable modem, has no problems seeing the site in its new location.

It appears that my iBook is the only machine affected. That's why I'm not sure where the problem lies. I'm not sure if its a problem with my machine, or if the router that my ISP is routing me thru has a problem. Although both computers in my office are using the same cable modem, in the Network Preferences, each computer is evidently being routed thru a different router at our ISP.

So like I said, I'm stumped. I have no idea where the fault lies, and have tried everything I can think of to solve the issue... all to no avail.

Try and open Terminal and write:

host -a www.eliteinteractive.com

See if the problem disappears.

There is a problem with the name servers as I suspected, and one of your machines seems to be contacting the same name server all the time.

Your domain is listed in two name servers (ns1.praevius.com and ns2.praevius.com), and ns2.praevius.com points to 66.223.21.81 while ns1.praevius.com points to 66.223.21.80.

NeXTLoop · Feb 16, 2003, 05:11 PM

Actually, both I.P. addresses just point to the same server that hosts multiple domain names. The server also acts as its own DNS server.

Most of the domains are all assigned to the first I.P. address, 66.223.21.80. www.eliteinteractive.com is the only one that is on 66.223.21.81. So I don't think its the way the name server is set up.

NeXTLoop · Feb 16, 2003, 05:15 PM

YEEEEHAAAAAAAA!

Sorry, had to get that out.

All of a sudden, it appears to be working. I'm now pinging the right address, and can access the site just fine. I'm back to my original theory that it has to do with that router that my ISP is routing me thru.

I've actually been gone to a friend's house the last couple of hours, and when I got back it was working.

But again, thanks for the help everyone. I did learn a few things that will prove useful in the future.
