Question: Can I use scripts when accessing a website via an IP address instead of a domain name?

[geigel]

I access my router's admin area via a web interface using the IP address of the router. I would like to use Witchcraft to manipulate an admin page that is incredibly difficult to work with (e.g. I want to rearrange the UX/UI of certain elements to make it more readable). Is there a way to do this? What would I name the script file?

IP_ADDRESS.js, that's literally it.
