Flagged prefixes
| Prefix | Family | Addresses | Country | Flags |
|---|---|---|---|---|
| 137.164.50.176/28 | IPv4 | 16 | US | Too specific |
| 2607:f380::118:9a43:2b00/120 | IPv6 | /120 | US | Too specific |
A flag is an observation, not an accusation. Very large and very specific prefixes are both legitimate in the right context.
