Summary

Mainova AG

Germany · AI-generated

utility corporate energy frankfurt

MAINOVA-AS is the autonomous system for Mainova AG, a major regional energy and water utility based in Frankfurt.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by netnames MAINOVA-AG-NET and MAINOVA-NETWORK and a reverse DNS entry test-coremedia.mainova.de.
  • The AS announces 1280 IPv4 addresses across 3 prefixes with only 2 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.

Notable

  • All registrants for the announced prefixes are Mainova AG Network Management, fully consistent with the AS holder.
  • The address inventory is finely subdivided into three small blocks, typical of an internal corporate estate segmented by site or function.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-21, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation

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 1,779 prefixes, as published 2026-10-22. 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.
