Hi All,
I am working on the proprietory Dynamic DNS client implementation . My DHCP and DDNS server are running on LINUX and would like to know some information about Secondary & Tertiary DNS Servers.
Currently, my client send the update to only Primary DNS server.

Could anyone kindly answer the following :
Why do we need secondary and tertiary servers?
My understanding regarding them is that :
- Any client sends the update only to the Primary DNS server.
- Primary server updates the records to secondary and tertiary.
- Any DNS Queries can be answered by any of the primary, secondary or tertiary servers.

Should client send the update record to secondary DNS Server if primary is not reachable?

Thanks in advance,

With Regards,
nsvora
