 This is a list of valid fully-qualified domain names (FQDNs) and/or IP addresses that can be used to reach the NetBox service. Usually this is the same as the hostname for the NetBox server, but can also be different; for example, when using a reverse proxy serving the NetBox website under a different FQDN than the hostname of the NetBox server. To help guard against [HTTP Host header attackes](https://docs.djangoproject.com/en/3.0/topics/security/#host-headers-virtual-hosting), NetBox will not permit access to the server via any other hostnames (or IPs).

 The value of this option is also used to set `CSRF_TRUSTED_ORIGINS`, which restricts POST requests to the same set of hosts (more about this [here](https://docs.djangoproject.com/en/stable/ref/settings/#std:setting-CSRF_TRUSTED_ORIGINS)). Keep in mind that NetBox, by default, sets `USE_X_FORWARDED_HOST` to true, which means that if you're using a reverse proxy, it's the FQDN used to reach that reverse proxy which needs to be in this list (more about this [here](https://docs.djangoproject.com/en/stable/ref/settings/#allowed-hosts)).
