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.
What happens when the primary server is not
reachable?
Should DDNS client send the update record to
secondary DNS Server in that case?
Note:
I have proprietory implementation of DHCP and DDNS
client so i dont want to have DHCP server
updating the DNS server.
Thanks in advance,
With Regards,
nsvora

| The 2nd and 3rd DNS servers are redundancy
measures. The other things that you are talking
about are implementation specific. ____________________

Thanks for the reply David.
My understanding is that updates should be sent
only to the currently configured primary server.
Secondary and Tertiary servers should be by client
only for redundancy of DNS queries i.e there should
be no redundancy for the updates. Am i right? |
