Step 2: Start VNC Viewer on the client computer
This section assumes VNC Viewer is available on the client computer. For more information, see Setting up
the client computer on page 12.
To start VNC Viewer, double-click an appropriate icon, or open a Command or Terminal window and:

Step 3: Identify VNC Server running on the host
computer
You must uniquely identify VNC Server running on the host computer you want to control.
If you are connecting within a private network such as a LAN, enter the network address of the host
computer itself in the VNC Server dropdown. This address can take the following forms:
• A host name for the host computer, for example johndoe. (Note the computer may not have a host
name.)
• An IP address for the host computer in IPv4 format, for example 192.168.0.133.
• An IP address for the host computer in IPv6 format within square brackets, for example
[2001:db8::1]. (Note IPv6 may not be enabled.)
If you do not know the network address of the host computer, start with Connecting within a private network
on page 27.
If you are connecting over the Internet, and the host computer is protected by a router, then enter the
network address of the router in the VNC Server dropdown instead. If you do not know the network address
of the router, see Connecting over the Internet on page 28.
