I see this in Settings, but not the ipv6 address.
Tried ifconfig
en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=6463<RXCSUM,TXCSUM,TSO4,TSO6,CHANNEL_IO,PARTIAL_CSUM,ZEROINVERT_CSUM>
ether a0:78:17:80:b0:63
inet6 fe80::872:f16d:4262:fcbe%en0 prefixlen 64 secured scopeid 0xb

nd6 options=201<PERFORMNUD,DAD>

But I was told, this is not real ipv6 address, but localhost or loopback: fe80::872:f16d:4262:fcbe
