Abstract
Systems, methods and articles of manufacture are disclosed for updating IP addresses on a private network. A DNS server receives an updated IP address and stores both the updated IP address and an old IP address. The DNS server includes the updated IP address in responses to all DNS query requests, wherein the DNS query requests are to the old IP address. Further, the DNS server deletes the old IP address and updates the DNS server network settings with the updated IP address after every remote client on the private network has stored the updated IP address.
