DNS reverting to entry that existed for 5 minutes

I wanted to set up a bonded ethernet interface on my Synology NAS so i plugged in LAN port 2 and it was set to DHCP so the Windows AD DNS server assigned it 192.168.2.9. i changed that interface on the synology to manual static and assigned 192.168.3.104. LAN port 1 has always been assigned 192.168.3.100.

It didn't change in the Windows DNS server so i deleted the entry and removed the synology NAS from the domain and added it back and the DNS record correctly showed 192.168.3.100. Then a little while later it reverted to the incorrect 192.168.2.9, so i opened the DNS entry on the AD server and manually changed it to 192.168.3.100. Then over the weekend it again reverted to 192.168.2.9. How do i stop it from reverting again and again?

    Hello,

    Are both LANs connected to the domain network?

    What's the current way of obtaining address for these two LANs?

    Best Regards,

    Wesley
