- * Example enumeration:
- * [ no subnet ]
- * ::1/128 - address
- * ff00::%1/8 - multicast (no IPv6 broadcast)
- * 127.0.0.0/8 - subnet
- * 127.0.0.1/32 - address
- * 127.255.255.255/32 - subnet broadcast
- * 224.0.0.0/4 - multicast
- * 255.255.255.255/32 - broadcast
- *
- * Which differs from most adapters listing three IPv6:
- * fe80::%10/64 - subnet
- * fe80::51e9:5fe5:4202:325a%10/128 - address
- * ff00::%10/8 - multicast
- *
- * !IfOperStatusUp IPv4 addresses are skipped:
- * fe80::%13/64 - subnet
- * fe80::d530:946d:e8df:8c91%13/128 - address
- * ff00::%13/8 - multicast
- * [ no subnet ]
- * [ no address ]
- * 224.0.0.0/4 - multicast
- * 255.255.255.255/32 - broadcast
- *
- * On PTP links no multicast or broadcast addresses are returned:
- * [ no subnet ]
- * fe80::5efe:10.203.9.30/128 - address
- * [ no multicast ]
- * [ no multicast ]
- * [ no broadcast ]
- *
- * Active primary IPv6 interfaces are a bit overloaded:
- * ::/0 - default route
- * 2001::/32 - global subnet
- * 2001:0:4137:9e76:2443:d6:ba87:1a2a/128 - global address
- * fe80::/64 - link-local subnet
- * fe80::2443:d6:ba87:1a2a/128 - link-local address
- * ff00::/8 - multicast
