Hosting RIPE Enterprise
Summary
Arctic Tern
enterprise ipv6 icelandic
The AS handle ISEY-ASN is held by Arctic Tern, an Icelandic enterprise network operator.
What it's used for
- The space carries a single IPv6 prefix,
2a07:54c2::/36, with no IPv4 addresses announced. - With one IPv6 prefix and two observed neighbours, the network operates as a small-scale enterprise or regional provider rather than a large transit or access network.
- As an enterprise entity, the traffic consists of internal corporate or organizational endpoints rather than mass consumer subscriber traffic.
Notable
- The registry holder is listed as Kria Elinarbur, while the AS handle references Islands-Eystrasaltsfelagid hf, indicating a distinction between the current legal entity and the original registration.
- The address inventory is minimal, consisting solely of one IPv6 block, which suggests a specialized or limited-scope deployment.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-06, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
