IP adresss ranges in Auth0 Callback URLs

Hello, we would like to find a way to allow any Callback URL that follows the format of an IPv4 address in the hostname. The reason behind this is that the Web Application host is in the private network of the client company and not on the internet, so we do not use any domain. So, as the hostname oof the WebApp is the IP address of the Web Application server, which chosen by the client company, it is crutial to handle this situation because the chosen IP address could vary a lot. Is there any way in Auth0 to solve this situation? The wildcard (*) character has not been useful in this case.
Thanks for your attention.
