Aging and scavenging together provide a mechanism for removing stale resource records. These resource records can accumulate in DNS zone data over time when computers permanently leave the network. For example, if a computer registers its host (A) resource record at startup and is later disconnected from the network, its host (A) resource record might not be deleted. If your network has mobile users and computers, this situation can occur frequently.
