Summary

Stone Computers AD

Bulgaria · AI-generated

business integrator cloud

STONE-AS is operated by Stone Computers AD.

What it's used for

  • The address space carries corporate infrastructure, with netnames StoneComputers, STONE-NET, and STONE-BG identifying the operator's internal segments.
  • The AS announces 768 IPv4 addresses across 3 prefixes and maintains 3 observed neighbours, a ratio consistent with a business network rather than a transit provider.
  • Traffic from this AS consists of business applications, cloud service endpoints, and system integration infrastructure, reflecting the company's role as a Bulgarian IT system integrator and cloud provider.

Notable

  • Registrants align with the announcer, listing Stone Computers AD and A1 Bulgaria EAD for the respective prefixes.
  • The inventory consists of three distinct /24 blocks, indicating a segmented corporate estate rather than a contiguous allocation.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
