+title: Curl request with Host Header
+---
+
+## Why
+
+Sometimes when you're testing NGINX or a WAF, you won't have a DNS record set up for it yet, so can't get to the virtual host.
+
+## How
+
+Below is an example making a curl request to an IP address with the Host being `not.relevant-land.fyi`
+
+```shell
+curl --header 'Host: not.relevant-land.fyi' http://172.16.0.1
+```
