Summary
Knipp Medien und Kommunikation GmbH
hosting dns business
KNIPP-AMS-AS is operated by Knipp Medien und Kommunikation GmbH.
What it's used for
- The address space carries infrastructure for domain name registration and DNS services, evidenced by netnames
KNIPP-AMS,TANGO-AMS, andironDNS-NG1, and reverse DNS entries likeip0-49-253-195.dmz.ams.knipp.de. - The AS announces 2816 IPv4 addresses across 4 prefixes and 3 IPv6 prefixes, while maintaining 116 observed neighbours; this ratio of modest address inventory against a high neighbour count indicates a transit or peering-heavy role rather than a large access network.
- Traffic from this AS consists of web and API endpoints for domain registration systems, DNS resolution services, and IT enterprise solutions provided to business clients.
Notable
- All registrants for the announced prefixes are listed as
Knipp HostmasterandKNIPP Abuse Contact, which aligns directly with the AS holder. - The address inventory is finely subdivided into four distinct IPv4 blocks and three IPv6 /48s, reflecting an internal corporate estate segmented by service type (e.g., DMZ, untrust, Tango, ironDNS).

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: 445 networks and 1,817 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.
