Summary
ITENOS
transit nsp germany
AS50533 is operated by ITENOS (I.T.E.N.O.S. International Telecom Network Operation Services GmbH).
What it's used for
- The address space carries corporate and enterprise traffic, evidenced by netnames
DE-ITENOS-20180104andDE-ITENOS-20171116for the majority of prefixes, andBERSE/BER-DEfor the Berner Omnichannel Trading Holding SE blocks. - With 19,968 IPv4 addresses announced across 7 prefixes and 148 observed neighbours, the high neighbour-to-address ratio indicates a transit or network service provider role rather than an access network.
- As a Network Service Provider (NSP) in Europe, the traffic consists of upstream transit and peering connections for its customer base, including corporate entities like Berner Group.
Notable
- Registrants for the largest prefixes (134.101.64.0/19, 145.14.224.0/20, etc.) align with the announcer, listing ITENOS Netmaster and I.T.E.N.O.S. International Telecom Network Operation Services GmbH.
- The two /24 prefixes (192.109.121.0/24, 192.109.122.0/24) are registered to Berner Omnichannel Trading Holding SE, indicating specific corporate holdings or leased space within the AS.
- The inventory includes two /32 IPv6 prefixes (2a00:17f1::/32, 2a00:17f4::/32) alongside the IPv4 blocks.

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 1,783 prefixes, as published 2026-10-17. 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.
