Are there any cases where the info in the SOA record or the
@ NS records for a domain or subdomain is used in a DNS name resolution?
Let's say that I do not publish any SOA or
@ NS records on the
josh.com name server, would this have any impact on anything?
Asked differently, is there ever a time that I would expect my private DNS server for the
josh.com domain to get a query for
@ NS records or for the SOA record?
Say I have my own private DNS server for the domain josh.com. The registrar has the IP address of this name server and publishes it to the TLD servers.
I want to resolve
I ask root NS servers for
com.and they answer with the
comNS records in the authority section with IP addresses for the
.comGTLD servers in the additional section.
Then I use the IP address for one of the GTLD servers that was returned from the previous step to ask for
josh.com.and it answers with the
josh.com.name servers in the authority section along with their IP addresses in the additional section.
Finally, I ask one of the
josh.comservers that were returned from the previous step for
www.josh.com.and get an answer in the answer section.
Is seems that no SOA or
@ NS records are ever touched here?
