isp fiber residential hts

NTS-HUNTSVILLE-01 is operated by Vexus Fiber.

What it's used for

  • The address space carries residential and business fiber services, evidenced by netnames VEXUS-CGNT-NET-2, VEXUS-HUNTSVILLE, and NTS-HUNTSVILLE.
  • The AS announces 1792 IPv4 addresses across 4 prefixes with 2 observed neighbours, a ratio consistent with an access network providing local connectivity rather than transit.

Notable

  • Registrants align with the announcer for three prefixes under Vexus Fiber, while the smallest prefix 38.172.108.0/24 is registered to NTSC, suggesting historical or leased space.
  • The inventory consists of four distinct IPv4 blocks with no IPv6 prefixes announced.

Reputation

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: 451 networks and 1,853 prefixes, as published 2026-11-04. 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.
