Consider the following scenario:
This issue occurs because of a timing issue between the DNS Server service and the DHCP client.
Upon start, by default, the DHCP client tries to verify whether the previously assigned lease is still valid. In the above described scenario however, it cannot reach the DHCP server, therefore it takes more time to keep the previously used IP Address.
If the DNS service starts while the DHCP client is still validating, it will not find a valid IPv4 address to bind to.
Also, The DNS Server service registers for IP address change notifications to make sure that the service is informed of IP address changes, for example if the DHCP client service decides to keep the previous IPv4 IP address. However, the DNS Server service does not receive the notification if the computer receives an IP address in a certain time period. This certain time period is between when the service starts and when the service begins to listen for the IP address change notification. Therefore, the DNS Server service does not start by using a valid IP address if the computer receives the IP address in this certain time period.
