Summary

CSI Telecom Group

United States of America · AI-generated

business telecom web

The AS handle HCIS-1 is held by CSI Telecom Group, Inc.

What it's used for

  • The address space carries web services and corporate infrastructure, evidenced by netnames WEBSERVICES and CSI-TELECOM-GROUP-INC.
  • The inventory consists of 19 IPv4 prefixes covering 6,656 addresses, with a neighbour count of 3, indicating a small-scale access or business network rather than a transit provider.

Notable

  • Registrants are predominantly CSI Telecom Group, Inc, with exceptions for Systems Solutions of Paducah, Inc. and MyChoice Internet on specific /24 blocks.
  • The address inventory is finely subdivided into /23 and /24 blocks, consistent with an internal corporate estate or small ISP segmentation.

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: 442 networks and 1,783 prefixes, as published 2026-10-20. 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.
