What it's used for

• The address space carries enterprise traffic, evidenced by reverse DNS entries such as a0ca8640.arctictern.is and netnames IS-ARCTIC-TERN-20241003 and IS-ARCTIC-TERN-20250930.
• The AS announces 512 IPv4 addresses across 2 prefixes and 4 IPv6 prefixes, with 3 observed neighbours, indicating a small-scale internal corporate estate rather than a transit or access network.
• Traffic from this AS consists of internal corporate endpoints and services for the Arctic Tern organisation.

Notable
