Summary

MKQ Internetservice

Germany · AI-generated

hosting residential germany small-isp

MKQ-AS is operated by Manuel Krebs trading as MKQ Internetservice.

What it's used for

  • The address space carries server infrastructure, evidenced by reverse DNS entries such as server5376.l.server.mkq.de and server1664.l.server.mkq.de.
  • The AS announces 4,864 IPv4 addresses across 11 prefixes and maintains a single observed neighbour, indicating a small-scale access or hosting network rather than a transit provider.
  • Traffic from this AS consists of hosted servers and associated services, consistent with the operator's role as a small German internet service provider.

Notable

  • Registrants across all prefixes consistently identify "Hostmaster MKQ" and "MKQ Internetservice", aligning perfectly with the AS holder.
  • The inventory is composed of multiple /22, /23, and /24 blocks within the 146.247.0.0/16 range, reflecting a fragmented but cohesive address estate.

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.
