Using the Windows hosts file, one can redirect traffic for a domain to a specific IP address, e.g.

domainA.com --> 127.0.0.1

I am looking for a SIMPLE way to do the same, but for a target domain name not for a target IP address (as this is dynamic), I.e.

domainA.com --> domainB.com


Addition: After the getting some initial answers I think I need to concretise my question.

Situation: I have an application which looks up the IP of the target domain via DNS and then connects via HTTP to the IP address. I do not have control over any proxy settings.

Option 1 Basically I am looking for a way to:

  • intercept DNS requests for a domainA.com
  • launch a DNS request for a domainB.com
  • serve the IP of domainB.com in response to the request for domainA.com

Without running an entire DNS server.

Option 2 If a DNS server is the only way, in the alternative I would also be happy with an solution to how to define a non-standard DNS-server for a single application. Any ideas for wrapper applications, etc?
