It would be useful to be able to define the ntp server in iHost settings (I’ve suggested this previously) and set the iHost ip address manually rather than have to rely on the router DHCP server for mac- ip reservation.
This way is better because it avoids potential conflicts. Besides, assigning an address in this way always works reliably.
That is lazy way to manage a network- where possible we tend to allocate fixed ip addresses and keep up-to-date records.
