Summary

United States of America · AI-generated

business private us

The AS handle FLYINGJ is held by F J Management Inc.

What it's used for

  • The address space is registered under the netname FLYINGJ for F J Management Inc., indicating a private corporate estate rather than a public service provider.
  • The AS announces 2816 IPv4 addresses across 6 prefixes with only 2 observed neighbours, a ratio consistent with a small internal network or site-specific infrastructure.

Notable

  • All registrants in the RDAP data match the announcer, consistently listing F J Management Inc. for every prefix.
  • The inventory consists of six contiguous or near-contiguous blocks within the 204.110.224.0/22 range, suggesting a single logical allocation subdivided for internal use.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 452 networks and 1,853 prefixes, as published 2026-11-05. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
