Hi, I have uploaded my site on two servers. I want to use one as a primary server and the second like a backup in case the first goes off-line. I'm experimenting with the name servers, but it seems to choose servers randomly. I set ns1 & ns2 to first server and ns3 & ns4 to second. Any suggestions?

Never mind the documentation - a 2 minute test shows that the hosts file overrides your DNS server. Try putting microsoft.com or whatever other host name you like in your hosts file with a redirection to some other IP, and then do a NSLOOKUP on that host name. You will see that it goes to the IP you specified in the hosts file, not what your DNS server says. What is confusing though is that even though it got the answer from the Hosts file, NSLOOKUP will say that it got the answer from your DNS server - but it is lying.

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

What you're trying to do isn't possible. An IP address can't
be mapped to another IP address in that way. The hosts file
is all about mapping *names* to addresses.

I don't know of a solution for your application, short of
trying to patch the binary.

I can't seem to redirect an IP to an IP in the hosts file. I have a desktop application which references an IP that is no longer valid and I don't have the source code. I want to fake the PC into thinking that the old IP is referring to the new IP.

Say my old IP is 1.2.3.4 and my new IP is 1.2.3.5, I want the host file to say something like this:

1.2.3.5 1.2.3.4

This doesn't work though, any ideas?

Is there a way to forward the index page to the test site using an html tag?

Remember, the hosts file overrides DNS, so if the real IP address for example.com changes again sometime in the future, this machine will continue to believe it's at whatever IP address is listed in hosts.

EndQuote

This is not true, all over the microsoft website it is said that the DNS is read FIRST and the HOSTS file read SECOND. This is a problem for me because I am trying to give a different IP for a hostname and I am unable to because the hostname is first resolved via DNS so Windows does not bother checking HOSTS.

Definetly works for static IPs. Don't understand how a machine being shared or not (in any of several definiteions of 'sharing') makes a difference though.

Good trick. I supose it will work well if you have a your own server with a static IP address, but probably will be dificult if your domain is hosted in a shared machine. Any idea for this?
