virtualhost - Web server showing IP address instead of domain name

I'm running a web server (Apache2) on CentOS 7. I have the following virtual host file. The site is being served as it should. However, the URL is changed in the browser (any browser) from the domain name verizondecom.com to the server's IP address.

What needs to be changed so that the URL is the domain name and not the server's IP?

NameVirtualHost *:80



   ServerName www.verizondecom.com
   ServerAlias verizondecom.com
   ErrorLog /var/log/httpd/verizondecom.err
   CustomLog /var/log/httpd/verizondecom.log combined
   DocumentRoot /var/www/www.verizondecom.com/public
   SetEnv ENVIRONMENT "production"

   AllowOverride ALL

   Order allow,deny
   Allow from all
   Require all granted
