Internal Network lets you communicate with other VMs with
the fastest speed possible, and also enables Internet access. Always use
this network to communicate between VMs.
Research Network lets you communicate with the VM from
the CiTIUS wired network, useful to enable direct SSH access or deployments
using reverse proxies. The number of IP addresses is very limited, so use
only if needed. However, if you require more IP addresses, ask the system
administrators.
To be able to edit networks,
the VM needs to be powered off.
