Summary
FAL Networks
enterprise legacy
FN-205-4138 is FAL Networks, a small independent network operator registered in
Tryon, North Carolina.
What it's used for
- A minimal routed presence: a single IPv4
/24alongside a comparatively large IPv6 footprint, taking transit from a few upstream providers. - Public information about the network is thin, and the registry does not describe a service offering, so its purpose is best left undescribed rather than guessed at.
Notable
- The IPv4-to-IPv6 balance is inverted relative to most networks of this size: one IPv4 prefix against many IPv6 blocks, which is a pattern seen in IPv6-forward and experimental deployments.
- Despite the low number, this is a modern holder. ARIN registered both the organisation and the autnum in 2017, so AS4138 was reissued and carries no early-internet pedigree.
Interesting
- Very low ASNs occasionally resurface with new, small owners after being returned to the RIR pool, which is why the number alone is a poor guide to a network's age or importance.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
No IC3 indicators Nothing from the FBI IC3 feed.
Threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
