5. If this fails because the A entry already exists, an update is sent for the A record with the name, the
prerequisite being that the TXT record must have the same hash.
6. It next sends a PTR update.
When the lease expires or when the client sends a DHCPRELEASE, the A and PTR entries are deleted.
When an update all command is issued to a DHCP server, all leases issued by the DHCP server will be updated
on the DNS server. As this command may take considerable time to complete, it runs asynchronously. You may
view the status of the last update all command at any time.
If the update of a DDNS entry fails, it is recorded and the update all process continues with the next entry.The
status displayed will be as follows:
• If no update command has been issued since system bootup: No manual update initiated
• If an update is in progress: Update being performed: [x total, y completed, z failures]
• If an update completed with no failures: Completed x updates successfully
• If an update had failures: Update failed: [x total, y failed]
