DNS Aging/Scavenging & DHCP lease duration recommendation

Dear All,

I would like to as whether is there a recommended setting for DNS Aging/Scavenging & DHCP lease duration?

For example, if the lease duration is 8 days, so do I have to configure the DNS Aging/Scavenging for more or less 8 day?

Thanks

In my experience, i have always had the DNS scavenging set to the same time as the DHCP lease duration.

There's nothing wrong with the default settings in Windows.  If the DHCP lease is 8 days, it renews in 4 anyway...

Microsoft will tell you to use the default values unless you need to ameliorate traffic on your network.  Do you have a large number of DHCP clients?  Are you running out of IP addresses?  Do you have a large number of machines that are mobile (in and out of the office)?  Do you have a large number of machines that are often turned off?  Unless you answer yes to any of these questions, you're probably okay.

I would stick with the default settings unless you are having issues.  Are you by any chance experiencing any problems?

You can always use DHCP server to dynamicaly register DNS records and remove them if they no longer are necessary. Then you don't have to worry about DNS Aging and Scavengind the best settings :)
