HP Imaging and Printing Security Center 2.0 - Tracking Device Identity
3
When IP addresses are provided, deselecting the Resolve IP addresses to hostnames
on add checkbox disables DNS resolve and results in displaying only the IP address
during the add devices process. This can be desirable in the absence of a DNS server or if
an IP address timeout is expected (typically within 5 seconds). If adding devices by
hostname or DNS alias, the DNS resolve to IP address occurs automatically. As the final
step, devices from the Devices to Add table are added to the database and assigned a
license by selecting OK.
DETAILED DESCRIPTION
RESOLVE IP ADDRESS TO HOSTNAME
The tracking of HP IPSC device identity depends on how the device was added and entered
into the database. The following section provides a detailed explanation of the process.
When the Resolve IP addresses to hostnames on add box is selected and an IP
address is provided without a correlating hostname, the IP address DNS resolve process is
as follows:
1. A reverse DNS lookup is performed on the IP address.
2. If resolved to a hostname, a forward DNS lookup is performed on that hostname.
3. The hostname must resolve back to the IP address to be valid.
4. If any address resolve step fails, the device is still staged displaying the IP address only.
5. If reverse and forward address resolve succeeds, the IP address is staged with the
hostname.
6. Once the device is entered into the database, IPSC uses the hostname as the primary
device identifier.
