AS4138 — FN-205-4138 - FAL Networks
AS4138 announces 1 IPv4 prefixes covering 256 addresses and 2 IPv6 prefixes.
About this network
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 /24 alongside 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.
