Hmm... The way that your system sets up this secondary address makes it show
up in QNetworkInterface as a separate interface:
Interface: "wlp2s0"
index: 2
flags: Up,Running,Broadcast,Multicast
hw address: 5C:51:4F:7C:49:F8
address 0: 10.0.0.108/24 (255.255.255.0) broadcast 10.0.0.255
address 1: fd2d:2122:f24:0:65d8:a47f:c825:2fe5/64
(ffff:ffff:ffff:ffff::)
address 2: fd2d:2122:f24:0:5e51:4fff:fe7c:49f8/64
(ffff:ffff:ffff:ffff::)
address 3: 2601:1c0:5803:81c9:65d8:a47f:c825:2fe5/64
(ffff:ffff:ffff:ffff::)
address 4: 2601:1c0:5803:81c9:5e51:4fff:fe7c:49f8/64
(ffff:ffff:ffff:ffff::)
address 5: fd2d:2122:f24::9bd/128
(ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff)
address 6: fe80::5e51:4fff:fe7c:49f8%wlp2s0/64 (ffff:ffff:ffff:ffff::)
Interface: "wlp2s0:foo"
index: 2
flags: Up,Running,Broadcast,Multicast
hw address: 5C:51:4F:7C:49:F8
address 0: 10.0.1.108/8 (255.0.0.0) broadcast 10.255.255.255
Both interfaces have the same interface index, which is bad for multiple
reasons.
I did some changes for QNetworkInterface for Qt 5.2 that may have caused this
problem. I will look into changing it so that the information is merged. The
extra interface name will be lost (good riddance!).
