Summary
Ålands Telekommunikation Ab (Alcom)
isp legacy
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.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
