Summary

Mayr-Melnhof

Austria · AI-generated

business corporate manufacturing it

MAYR-MELNHOF is operated by Mayr-Melnhof MM Service GmbH.

What it's used for

  • The address space carries internal corporate IT infrastructure, evidenced by registrants MM IT NOC and netnames AT-MAYR-MELNHOF-20160330 and MAYRMELNHOF.
  • The AS announces 1280 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, with only 3 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of office workers, internal systems, and web/API endpoints for the Mayr-Melnhof group, a major European paper and packaging manufacturer.

Notable

  • Registrants MM IT NOC and MM Service GmbH align with the announcer, confirming the space is owned and managed by the corporate IT department.
  • The address inventory is finely subdivided into three distinct IPv4 blocks, consistent with site-by-site segmentation for a large industrial enterprise.

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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
