When writing an application for checking delegations, I identified the
following addresses as "bad" for nameservers of "public" zones:

    # 1. Link 0.0.0.0 plus 0.0.0.0/8
    # 2. Localhost net 127.0.0.0/8
    # 3. Privat net 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16
    # 6. Autoconfiguration for DHCP 169.254.0.0/16
    # 7. Example addresses 192.0.2.0/24
    # 8. Multicast 224.0.0.0/5 (224/8--239/8)

In the draft 2 (partly) and 3 are included. Should the other addresses
also be included?
