Summary

509Fiber

United States of America · AI-generated

fiber residential isp small

The AS handle 509FIBER is held by 509Fiber.

What it's used for

  • The space carries residential fiber internet service, as indicated by the netname 509FIBER and the operator's public description of providing "reliable service" with "unbeatable speeds" for homes.
  • The AS announces 256 IPv4 addresses and 1 IPv6 prefix, with only 1 observed neighbour. This low neighbour count relative to the address space suggests a small, local access network rather than a transit provider.

Notable

  • The registrant 509fiber matches the AS handle and the announced prefix 23.186.8.0/24, indicating direct ownership of the address space.
  • The address inventory consists of a single /24 block and one /36 IPv6 prefix, representing a compact footprint typical of a regional fiber provider.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
