How to Delete Static DNS record?(Infinite regeneration even when deleted)

Hi, My name is Juhyun in KOREA

I am the operator of the dns server and I have a question.

The static dns host(A) continues to regenerate even if it is deleted.(Windows Server 2016 DNS Service)
But I don't know what the problem is. Have you ever solved a problem like this?


Please Help me and have a nice day.
Thank you very much.

Open the DNS server console, highlight the server on the left pane, and then right-click Properties. On the Interfaces tab, select listen on only the following IP addresses. Remove unwanted IP address from the list.

So what we need do is :

1.Uncheck Register this connections Address in DNS.

2.Select listen on only the following IP addresses. Remove unwanted IP address from the list in interface tag.

3.Remove unwanted IP address in Name server tag.

Hope this can help you.

Hi ,

Windows-based computers that have static IP assigned will register their records in DNS every 24 hours.

If you don't want Static DNS record to be registered in DNS, go to clients' IPV4 advanced TCP/IP settings and uncheck Register this connection's addresses in DNS. As picture below:

Hi CandyLuo,
First of all, I appreciate for your kind reply.


I followed your direction ("Register this connection''s addresses in DNS" option uncheck)

but the record is continuously regenerated.
I'm not sure what the problem is. Is there anything else I need to check?

Thank you again for your answer.

Hi ,

Before going further, I would appreciate your help in clarifying the following situations:

This static record belongs to domain member or DC/DNS? Did you have multiple adapters on your machine? Please clarify more details to help us identify your issue.

If you have multiple adapters on your DNS server, then the DNS service will register the interface "Host A" record that it has set to listen on. Check the Name server tab list out the IP addresses of interfaces present on the DC/DNS then remove unwanted IP address from the list.

As picture below:

I'm sorry I should have explained it in detail.

I use windows server 2016, and I user multiple network adapter for a Disaster Recovery and backup.(3 network adapter exist)


have performed both steps you told me(Deleted both Record and IP, Uncheck DNS option)

A record and IP are re-created after a certain period of time.
OMG...TT


Is there any more action we can do?
Please understand that I can't upload it by capturing it because it's the company's security regulations.
