Flagged prefixes
| Prefix | Family | Addresses | Country | Flags |
|---|---|---|---|---|
| 186.249.222.0/25 | IPv4 | 128 | BR | Too specific |
| 186.249.222.160/27 | IPv4 | 32 | BR | Too specific |
| 186.249.222.192/26 | IPv4 | 64 | BR | Too specific |
A flag is an observation, not an accusation. Very large and very specific prefixes are both legitimate in the right context.
