Ghost hostnames

Jump to solution

Every now and then after i connect iOS devices to my Mac to charge/ use/sync etc, then disconnect then, i find Hostname changes in ESXI..

Why does this happen?  It's really annoying, almost to the point, its just *asking* to be a statically set (Attached)

If I was to guess, I would look for a misconfigured router, that has an overlap between the pool of DHCP and fixed IP addresses, or two routers with overlapping DHCP address pools, one for Ethernet and one for Wifi.

Is the same DHCP Scope used for WiFi?
If yes you may an assign a static reservation to your Host.

It seems i found switching to "Host only" and  "Reset System Configuration" fixed the issue on host.. However Wi-fi- shares same DHCP scope on router..

So, the issue seems to be only when router issues .. Even when setting static on Host does nothing..

When I change back to "bridged" even after resetting system config on Host, it picks up "ghost' again...

I do have static IP on host with 192.x address, so would be be be the cause?

How can I have staticically set NAS and ESxi   co-exist without ghost appearing ?

The simplest answer is probably to simply change the host's address to one which is outside the DHCP allocation pool.

Alternatively, change the DHCP pool size on the router, so that the existing host address is outside the allocation range.

What methods are available to to will be dependent on the make and model of router.
