Unused IP address still showing up on 'Find.vi' Systems

[Eric_Simon]

I have a bunch of cRIOs on my local subnet.  I'm using 'Find.vi' Systems instance to find all of them from my host application.

I have had the cRIO IP addresses statically set to certain values for a few weeks.  I programmatically changed one's IP addresses from the host.

However, when I do another 'Find.vi', the old address of the one I changed shows up in the list along with the new address.  It almost seems like the addresses I have had them set to for a long time stick, but the new addresses don't.  For example, I had one set to 192.168.1.204 for several weeks.  I change it to 192.168.1.205 and both 192.168.1.204 and 192.168.1.205 show up in the list.  When I change it back to ...204, only ...204 shows up in the list.

Is there some cache that needs to be cleared to stop this from happening?  I've attached a screenshot of how I'm doing the 'Find'.

Thanks!

What happens when you make the include cached results to none?

I am not sure how the Find.vi looks for addresses but it is possible that it may use a name lookup on the network and teh old addresses may be cached in the name server.

Same results when I set it to 'None'.  I'm looking directly for IP's.  The two IP addresses show up for the same MAC address, which I thought was strange.  See the attached...

The old address is cached in either the name sertver or a network device ARP table.
