# What ports are publicly accessible?

Every client Application, Virtual Machine and Bare Metal host are assigned a unique Public IP address.  There are no ports or services blocked at the network layer.

Users should take best efforts to protect their instance including, for example, use of host-based firewalls ([ufw](https://wiki.ubuntu.com/UncomplicatedFirewall)) and intrustion prevention software ([fail2ban](https://github.com/fail2ban/fail2ban)).

{% hint style="info" %}
Network Firewall Services are under development for a future release of Denvr Cloud
