DNS Aging and Scavenging
Posted on 2014-04-24
We have just upgraded the workstations for one of our clients. All the attorneys at this site chose to go with Windows Surface Pros for their hardware. They have docking stations in their offices, but of course the Surfaces also have wireless so that they can move into a conference room and still be on the network.
My concern is about IP addressing issues and conflicts, so I want to be sure that the DNS aging and scavenging settings are optimized for this type of environment. I was thinking about reducing the aging/scavenging period (now set at 7 days) to something like 1 or 2 days, so that the IP addresses used by the wireless cards will not hang around for long periods of time without being used. However, I'm a little concerned about how/whether this would negatively impact network traffic or cause some other unforeseen issue.
Any sage advice based on actual real-world experience would be appreciated!
