Let's say that we're testing a webserver where the pages served depended on a domain that you don't own. The most common way I know to test this is to modify your `/etc/hosts` file to contain the hostname and ip address you want to map it to.
|
|
|
|
```
|
|
192.168.1.2 custom.domain
|
|
```
|
|
|
|
I've recently discovered that the command line utility `curl` has a quick and easy option to forge the hostname of a request.
|
|
|
|
```bash
|
|
curl --resolve domain:port:ipaddr url
|
|
```
|
|
|

There are also browser extensions that you can use such as [LiveHosts](https://github.com/Aioros/livehosts) to get around this as well. This post isn't entirely useful when talking about permanent services.
|
|
|
|
If this is going to be a publicly facing service, then you should just set the records of your domain name to point to the server.
|
|
|
|
If it's a non-public routable service, then perhaps try looking into setting up your own private [dns server](https://brandonrozek.com/blog/coredns/).
