fiber isp colocation business

IDL-76-53581 is held by Inland Fiber.

What it's used for

  • The address space carries fiber-to-the-home and business connectivity, evidenced by the registrant "Inland Fiber and Data" for 72.244.158.0/24 and the netname NET-66-92-58-0-24.
  • The AS announces 512 IPv4 addresses across 2 prefixes with 1 observed neighbour, a ratio indicating a local access network rather than a transit provider.
  • Traffic consists of residential and business broadband subscribers in Florida and Washington, as well as colocation clients served by the operator's data center facilities.

Notable

  • Registrants align with the announcer, listing "Private Customer" for 66.92.58.0/24 and "Inland Fiber and Data" for 72.244.158.0/24.
  • The inventory consists of two /24 blocks, representing a small, focused 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: 447 networks and 1,849 prefixes, as published 2026-10-30. 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.
