Hello,

I am just wondering how ntopng handle dynamic IP addresses modification.
So I test with two computers. I do the following:
- Set 192.168.1.1 on computer A
> ntopng associate computer A with IP 192.168.1.1
- Set 192.168.1.2 on computer A
> ntopng associate computer A with IP 192.168.1.2 so that there is now two
entries for the same computer
- Set 192.168.1.1 on computer B
> ntopng do not associate computer B with IP 192.168.1.1. Instead, it keeps
thinking that it is computer A and continue monitoring traffic as if it
comes from/to computer A.

Also when ntopng restore a host it do not check for its MAC address but
only for its IP address. So I set 192.168.1.1 on computer A then shutdown
ntopng and let it dump the redis data. Then I set 192.168.1.1 on computer B
and start ntopng again, it sees computer B with IP 192.168.1.1 and restore
the stats from redis wich belongs to computer A.

So my question is: is this a desired features ? Is there a plan to modify
this behavior (I am actually planing to change it) ?

Thank you,
Mathieu
