I am newbie

Please help me with the above question, thank you.

for example 192.168.20.1.
and 192.168.92.34

e.g. when you are setting up example.com zone:

ns1 = "ns1.example.com"
ns1.example.com = "ns1.example.com.example.com"
ns1.example.com. = "ns1.example.com"

Without dot means plus domain-name.
With dot means FQDN (Fully Qualified Domain Name).


I think IP address need no dot.

If you put a dot at the end of the IP address it will think it is a FQDN and it will of course fail.

thanks for your help, if i made any mistake in the example, please forgive me, as i am a newbie to DNS...
