Apache configuration file name without domain name

I have my Laravel project on an ubuntu 16.04 server and don't have a domain name. Now I should create the configuration file for my site to work with:

sudo cp /etc/apache2/sites-available/000-default.conf /etc/apache2/sites-available/mysitename.com.conf

what should the file name be instead of mysitename.com.conf as I don't have a domain name ??
