Hi,

 

I don't think Infoblox (DHCP Server) has feature to prevent mac address spoofing. May be security feature in the switch could be the answer like DHCP snooping and Dynamic ARP Inspection.

 

Thanks

Hello,

 

Of course we demote the Domain controller properly,  but the case that I am not responsible for the Infoblox DNS, and my customer complaining that there is some residual DNS record left after proper removal, which is not the same case as with Windows DNS server.

 

thanks
