They are generated by default based on qubes VM ID (qid)[1], which are unique. You can see it on `qvm-ls -O name,qid,ip`. But you can also set the IP explicitly (via qvm-prefs), and then it's up to you to avoid conflicts. BTW, it's also possible hide VM's "real" IP from the VM itself using a bit of NAT magic. You can set it with `qvm-features VMNAME net.fake-ip 1.2.3.4` (or any other IP). See qvm-features man page for details. The VM will see own address as 1.2.3.4. Address set this way does not need to be unique - you can have a set of VMs that all think they have the same IP (but still, the address set in the "ip" property needs to be unique).
