Summary

CRELCOM

Russian Federation · AI-generated

business russia corporate

The AS handle ONLINE is held by CRELCOM LLC.

What it's used for

  • The address space carries corporate infrastructure, evidenced by netnames such as CRELCOM-NET-9124796 and RU-CRELCOM-1-20150508 associated with CRELCOM LLC.
  • The network announces 16896 IPv4 addresses across 16 prefixes with a single observed neighbour, indicating an internal corporate estate rather than a transit or access provider.
  • Traffic from this AS consists of internal business operations and office connectivity for CRELCOM, a Russian telecommunications company.

Notable

  • Registrants are predominantly CRELCOM LLC, with some prefixes registered to Inna Khoruzhaya, suggesting internal administrative segmentation or historical registration practices.
  • The address inventory is finely subdivided into /22 and /21 blocks, consistent with site-by-site segmentation for a large corporate entity.

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 2026-10-17. 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.
