Dns issue

[said07]

In my dns I see multiple hosts with the same ip. Some ips have up to 3 hosts.
How can I prevent that from happening?

Thanks,

By the way, I set up scavanging about 3 weeks ago. But the issue still remains.

What are these devices/hosts?? Are they servers, printer, workstations? It makes a difference. If they are workstations then they are just changing IP addresses. Increase the DHCP time and it will help with that.

If they are other devices, they should have a static ip address which will take care of that. You don't put enough meat on the bone to understand your problem/environment.

they are workstations. I just did set the no-refresh/refresh to 7 days each and the dhcp to 8 days. We will see what happens.
Thanks.

If you don't need it, disable round-robin in the Advanced settings on your DNS server. If your workstation is added to an AD domain and has more than one IP address, the ability to resolve based on the 3 IPs is by design.
