It is pretty clear you don't understand what I'm asking.  The
information you've supplied are the configuration files for the
interfaces on the system and don't have anything to do with name resolution.

Looking back on what you said previously....

The DNS server tasked with returning the name for 192.168.1.69 is
192.168.1.1

This means the file /etc/resolv.conf on the system you've used the "dig"
command contains at least this line.

nameserver 192.168.1.1

That system is running the DNS server.  What system is 192.168.1.1?  And
did you setup the DNS server on that system?
