Domain configuration in tomcat- jsf applications

I have a jsf application running on the company server, using Tomcat 8.5. Currently I make the ip address of the server through the service of the site noip.com configured in my router. Only recently the service is failing. I would like to know if it is possible to configure my domain in tomcat without using providers. I have a domain registered in the registry.br. How would you point this out, since the IP of my internet provider is dynamic? Is this possible?
