I can't say anything definitive as all routers have their own wording for stuff. I would need to see for myself. Normally Dynamic DNS is used for something else - https://en.wikipedia.org/wiki/Dynamic_DNS.

In cmd, try:

Code:

nslookup
server 82.114.160.37
google.com

If it returns the IP addresses then it is a DNS server you are probably connected to.

Thanks a lot,

I am confused which is my automatic DNS server address?

1- Your command returned 82.114.160.37, and not 82.114.160.39

2- you think that 82.114.160.37 is automatic DNS server address? If so, then why does my router management interface: (first screen shot posted before) say:
Dynamic DNS Servers:
82.114.160.37
82.114.160.39

3- in the my router management interface are: (first screen shot posted before)
Dynamic DNS Servers addresses are two
82.114.160.37
82.114.160.39
However, with that command, only 82.114.160.37 is shown.

4- I have previously run the command 'tracert Google' , and its result was.

However, when rerun 'tracert Google' again, the result was completely different. I am stumbled by this.
