We can host many websites cause YunoHost is multi-domain and that some applications for websites management, like *WordPress* or *Web App Multi Custom*, are multi-instances, which means that the application can be installed many times.
#### Why can I access to applications via the IP address?
The [SSO](https://github.com/Kloadut/SSOwat/) does not allow access to the user part (apps included) via an IP address. For this purpose, you should use a domain name. One trick could be to modify the [`hosts` file (last §)](dns_local_network_en) of your desktop computer with a domain name that you don't need to own.
