Summary
GTT Communications Netherlands
hosting cloud legacy
GTT-AS is a small Dutch autonomous system of GTT Communications, the international carrier. GTT's main backbone is a different, much larger AS; this one is a legacy registration inherited through GTT's acquisitions in the Netherlands.
What it's used for
- Two /22s, about 2,000 IPv4 addresses, from
128.127.152.0/21. The RIPE netname on that space isNL-IRTCLOUD-20111017— Interoute cloud/virtual-data-centre addressing, from the pan-European carrier GTT acquired in 2018. - Eight observed neighbours and no downstream networks, so it functions as a service-hosting AS rather than as transit, despite the parent's carrier business.
Notable
- No PTRs came back on the addresses sampled inside the announced prefixes. That is not proof the reverse zones are undelegated, but it means rDNS offers no further evidence about what runs there.
- The AS was first seen originating
212.104.192.0/18back in 2000, a block it no longer announces. The number has been passed along through a chain of European carrier mergers.
Interesting
- The classification here follows the address space, not the holder. GTT is a transit carrier, but this particular AS carries a small pocket of hosted cloud addressing — a good example of why a subsidiary's AS should not inherit its parent's kind.

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.
