About this network

ALCOM is Ålands Telekommunikation Ab, trading as Alcom — the telecommunications operator for the Åland Islands, the Swedish-speaking autonomous region of Finland. Its NOC sits in Mariehamn.

What it's used for

• Broadband, TV, and telephony services for households and businesses across the Åland archipelago.
• Around 40,000 IPv4 addresses, distributed to subscribers rather than held for hosting.

Notable

• An eyeball network for a small island region: the address space geolocates almost entirely to Åland, which makes this ASN a clean proxy for "internet users in Åland".
• Alcom maintains an open peering posture, publishing peering contacts and a PeeringDB entry in its aut-num remarks — unusual diligence for an operator of this size.

Interesting

• Åland's separate telecom operator, distinct from mainland Finnish carriers, reflects the islands' autonomous status; the network boundary here follows a political one.
