Problem:

How to force eHealth to change the IP Address of existing elements with re-discovery
Can eHealth update the IP address of elements

Environment:  

eHealth 5.7
eHealth 6.x

Cause: 

If the NH_DISCOVER_UPDATE_IPADDR environment variable is set to yes, and discovery uses a seed file, it will force eHealth to update the IPADDR field of existing elements.

Resolution/Workaround:

If the environment variable is not set or discovery is done without a seed file, then it will only update the ipAddr field if the new value has never been seen on the device in any of the ipAddr or ifIpAddress fields from previous discover runs.
