[Github Issue] unbound: new ipv4 address of ntp.nic.cz
https://github.com/CZ-NIC/turris-os-packages/issues/1
DO NOT EDIT HERE! Copy fromThe server ntp.nic.cz has changed its IPv4 address. Hope the new one will be more stable.
BTW: the old address 217.31.205.226 still has reverse record of ntp.nic.cz.
