Summary

Alef Distribution RO SA

Romania · AI-generated

business it-distribution corporate

ALEF-AS is operated by Alef Distribution RO SA.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname ALEF-DISTRIBUTION-RO-SA on 193.142.250.0/24 and the registrant IPv4 Management SRL on 86.107.185.0/24.
  • The AS announces 512 IPv4 addresses across 2 prefixes with only 1 observed neighbour, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal business operations for an IT distributor, including office workers, web/API endpoints, and branch backhaul for Alef Group's Romanian operations.

Notable

  • Registrants align with the announcer's identity, with Alef Distribution RO SA listed for one prefix and IPv4 Management SRL for the other, suggesting a mix of direct ownership and managed IP space.
  • The address inventory is minimal, consisting of two /24 blocks, which fits the profile of a single corporate entity rather than a large-scale network operator.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,784 prefixes, as published 2026-10-19. 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.
