Summary

mpex GmbH

Germany · AI-generated

hosting datacenter business

MPEXNET is the autonomous system for mpex GmbH, a Berlin-based data center and IT infrastructure provider.

What it's used for

  • The address space is registered under the netname DE-MPEXNET-20051109 and is associated with mpex GmbH's data center operations.
  • The AS announces 4096 IPv4 addresses across 5 prefixes and 8 IPv6 prefixes, while maintaining 14 observed neighbours. This ratio of a moderate address inventory to a significant number of peering partners suggests a role focused on hosting and interconnection rather than pure transit.

Notable

  • All observed registrants for the announced IPv4 prefixes are mpex GmbH, which aligns perfectly with the AS holder and the MPEXNET handle.
  • mpex GmbH was founded in 2000 in Berlin with the goal of managing complex server environments and providing highly available IT infrastructure.
  • The IPv4 inventory consists of five contiguous blocks within the 81.17.208.0/21 range, while the IPv6 space is more extensively subdivided into eight distinct prefixes.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, 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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
