Secondary service has a following algorithm:
- DNS servers ns4-l2.nic.ru, ns4-cloud.nic.ru and ns8-cloud.nic.ru
(or ns4-l3.nic.ru,
ns4-l4.nic.ru,
ns4-l5.nic.ru, subject to the domain level)
requests the specified primary DNS server for zone transfer from the moment the provision of the service begins. - If the zone cannot be transferred from the primary DNS server at some point, the secondary DNS server will be repeating the zone transfer requests from time to time during four calendar days.
- If during four calendar days all requests of the DNS server for zone transfer are not successful, the DNS server will stop its attempts to perform zone transfer for a period of four calendar days.
- DNS server ns8-l2.nic.ru (ns8-l3.nic.ru, ns8-l4.nic.ru or ns8-l5.nic.ru subject to the domain level) requests the specified primary DNS server for zone transfer. If zone transfer from primary DNS server is impossible, it requests ns4-l2.nic.ru server (ns4-l3.nic.ru, ns4-l4.nic.ru or ns4-l5.nic.ru subject to the domain level ).
A notification of the errors occurred during the zone transfer will be sent to the technical email address ("mnt-nfy" field):
