Summary

HaCon Ingenieurgesellschaft mbH

Germany · AI-generated

business software corporate vpn

HACON is the autonomous system for HaCon Ingenieurgesellschaft mbH.

What it's used for

  • The space carries corporate infrastructure, evidenced by the reverse DNS record gate-vpn-01.hacon.de and the netname HaCon-Net.
  • The AS announces 256 IPv4 addresses within a single /24 prefix and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, isolated corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate communications and remote access for HaCon's employees, who provide software solutions for public transportation, mobility, and logistics.

Notable

  • The RDAP registrant for the announced prefix is Plus.line AG, Network Operation Centre, which differs from the AS holder, suggesting the address space is leased from Plus.line AG.
  • HaCon has been a member of the Siemens family since 2017, operating as a provider of software solutions for transport operators.
  • The address inventory is minimal, consisting of a single /24 block and one /48 IPv6 prefix.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, 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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
