Can't discover laptops which are being used remotely

[soko]

Hi. I have bunch of stale laptops that can't be updated. These laptops should be updated by SCCM and discovered by Discovery as scheduled. However, those laptops obtain different IP addresses when connected to the office network, SCCM also don't update them regularly and stay Stale. How can I discover/update these laptops? Thanks in advance.

The ip address changes everytime they connected to office network?

Can you identify the pattern when ip addresses are changing. I think they change within an IP range, so identify that ip range and enable discovery on ip range to discover those computers

Thanks for the prompt reply. I will check the pattern as you suggested.
But, why can't SCCM update it by name instead of creating Stale CIs (There must not be Stale CIs or duplicates due to changeable IP addresses.)? Is there any configuration for SCCM I should modify?

Can you compare the import set row data for these computers to compare which data is changing. If you are using SCCM Service Graph connector, the OOB transform maps uses a logic to run IRE to determine if a record exists or not . if exists it will update otherwise it will create it. So, check which attributes are changing for the same computer through SCCM imports?. For computers, I believe serial_number is the unique key to determine, but I need to double check to confirm
