business hosting leased us

BTC-BROADBAND is operated by BTC Broadband Inc.

What it's used for

  • The address space carries a mix of corporate and leased infrastructure, evidenced by netnames OLP, BTCBR, and COGENT-A.
  • Reverse DNS entries consistently use the olp.net domain (e.g., olp-209-150-244-0.olp.net), indicating a unified internal naming convention for the operator's estate.
  • The AS announces 25,856 IPv4 addresses across 13 prefixes with only 6 observed neighbours, a ratio that suggests an access or business network rather than a transit provider.

Notable

  • Registrants are mixed: most prefixes are registered to BTC Broadband Inc., but four prefixes (including 38.187.144.0/20 and 38.59.152.0/21) are registered to Cogent Communications, LLC, indicating leased space or historical acquisition.
  • The inventory is composed of various block sizes, ranging from /20s to /24s, with no IPv6 prefixes currently announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-01, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 447 networks and 1,843 prefixes, as published 2026-11-02. 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.
