moOde sometimes shows up LAN as <hostname>-2.local

[DRONE7]

Code:

:~$ sudo arp-scan --localnet  --ouifile=/usr/share/arp-scan/ieee-oui.txt --macfile=/etc/arp-scan/mac-vendor.txt
[sudo] password for bob:          


192.168.xxx.26    Raspberry Pi Trading Ltd
192.168.xxx.26    Raspberry Pi Trading Ltd (DUP: 2)

Interesting, often whilst booting MoOde and monitoring via arp-scan (to check when it is up and can be found from browser) there will appear 2 IP results both the same address but the second noted as "(dup-2)"

This resolves to one ip once fully booted.
