Summary

United States of America · AI-generated

business managed-services it

BTL is the AS handle for Bell Techlogix.

What it's used for

  • The space carries corporate infrastructure, evidenced by the netname SDL-BLK-4 and reverse DNS entries pointing to belltechlogix.com.
  • The AS announces 256 IPv4 addresses across 1 prefix with 2 observed neighbours, a ratio consistent with a small internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers and IT endpoints for a managed IT services provider serving enterprise and public sector clients.

Notable

  • The RDAP registrant for the announced prefix is Smithville Digital, LLC, which differs from the AS holder Bell Techlogix, suggesting a leased or historically allocated block.
  • The address inventory is a single /24 block, indicating a compact, self-contained network footprint.

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: 454 networks and 1,852 prefixes, as published 2026-11-08. 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.
