Extra IP when adding Isilon to Commvault as a storage array

We have 2 Isilon clusters, that I have added into Commvault as Storage arrays, on the Snap configuration Tab there is a tick box to Auto update array host aliases.

Site 1 - reports all ok

Site 2 - adds 3 extra IPs in 1.0.0.0, 9.0.0.0 and 243.16.85.145

I can manually delete these addresses, but we are also having some backup issues, so would be good to understand why this is happening.

I have logged a call with Dell support and using  isi_for_array -s ifconfig | grep -i "243.16.85.145" we were unable to find anything from an Isilon side.   They recommended I speak to my local network team.

My local network team have taken a look and they can't explain why site 2 unit comes back with these additional 3 addresses.

I have a call logged with Commvault, but as one is working ok, they will bounce me back to Dell

So I was wondering if anyone else on here has experienced anything similar or have any other ideas what could be causing this issue?
