Removal of "Register This Connection's addresses in DNS" and adding a static A record

    Question

  • Hi

    We are looking for the right way of removing the option "Register This Connection's addresses in DNS" from a NIC where we have multiple IPs configured and adding a static IP in DNS. Previously for one server we added a static IP for the server in DNS and then removed the option as well removed the dynamically registered DNS record, later after a few minutes we found even the statically created records got removed from Windows 2012 R2 AD integrated DNS. Looking for your support

    Thanks in advance

  • Hi,

    Thanks for your question.

    Based on my experience, if remove the option “Register This Connection's addresses in DNS” even if static IP is configured and once registers its record to DNS. After the scavenging interval, this record will be removed by DNS via the automatically scavenging setting of DNS. Did previous record removed has a timestamp?

    On the other hand, if you add a static record for the PC’s NIC in DNS console by manual, it is permanent and wouldn’t be removed by scavenging traditionally.

    Besides, I’m wondering of what do you would like to do about this scenario. Do you want to configure the NIC with multiple IPs ( static IP with multiple alternate IPs) ? Add a static record in DNS for this NIC’s primary IP?

    Hope this helps. I look forward hearing your good news. If you have any questions, please feel free to let me know.

    Best regards,

    Michael

  • Hi,

    Thanks for your update.

    I saw this article, doesn't signs that it's applies to Windows Server 2016. Just regarding this DNS setting on the server, I think there's no problem. Generally, it will go by above suggestion.

    Based on the situation and due to I'm a Network engineer, sorry for that I'm not be familiar with Exchange Server. Not very sure, what if this Exchange server setting, would it affect the DNS record of the server?

    I suggest you could also ask this thread in Exchange Server forum to resolve this issue.

    Highly appreciate your effort and time. If you have any questions and concerns, please feel free to let me know.

    Best regards,
