Add some default read-only system aliases
It would be useful to have some stock aliases that come by default which are not editable by users. These aliases would be somewhat of an extension to the choices we already have for things like "xxx Subnet" and "xxx Address".Some ideas:
- Local Networks
- ipv4_private (or perhaps rfc1918) - 192.168.0.0/16, 10.0.0.0/8, and 172.16.0.0/12
- ipv6_linklocal - fe80::/10
- ipv6_private - fc00::/7
- ipv6_multicast - ff00::/8
Having those available would save users from having to look them up, hardcode them, or make their own aliases for the same values on every system.
