Flagged prefixes
| Prefix | Family | Addresses | Country | Flags |
|---|---|---|---|---|
| 103.13.83.64/28 | IPv4 | 16 | AU | Too specific |
| 103.13.83.112/28 | IPv4 | 16 | AU | Too specific |
| 103.13.83.176/28 | IPv4 | 16 | AU | Too specific |
A flag is an observation, not an accusation. Very large and very specific prefixes are both legitimate in the right context.
