Do you need work in web development but project has not registered an IP yet? If you are using Nginx, and your server hosts several websites (vhosts) a way to do it could be this:
Note: this howto runs in a linux / debian7 server, and a fictitious domain "mydomain.net"
- In /etc/nginx/sites-available/mydomain.net change port to listen, for example:
- reload nginx configuration files:
service nginx reload
Then, you can get this web in this URL: MyServerIP:81 or MyServerDomain:81
