About this network

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.
