It seems there has been a significant reduction in the visibility of
certain routes in the IPFire dataset recently, and/or spurious routes
taking place of legitimate announcements.
For example, 209.38.204.47 is originated by AS14061 and announced in
209.38.192.0/19, but IPFire erroneously sees 209.38.0.0/16 and locates
no corresponding AS.
Here are a few more prefixes with the same issue:
+----------+------------------+-----------------+------------+
| ASN | Prefix | IPFire Prefix | IPFire ASN |
+----------+------------------+-----------------+------------+
| AS64425 | 45.148.122.0/24 | 45.148.120.0/22 | None |
| AS197540 | 94.16.116.0/22 | 94.16.96.0/19 | None |
| AS36352 | 198.23.234.0/23 | 198.23.128.0/17 | None |
| AS63949 | 172.105.192.0/19 | 172.104.0.0/15 | None |

Thanks so much for all your hard work,
