Summary
Tallink Grupp
shipping ferry corporate baltic
TALLINK-AS is held by AS Tallink Grupp.
What it's used for
- The address space carries corporate infrastructure for a major Baltic Sea ferry operator, with netnames
SILJANET2,SILJANET, andTALLINK-GRUPPall registered to AS Tallink Grupp. - The AS announces 4,608 IPv4 addresses across 3 prefixes in Estonia, with only 2 observed routing neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.
- Traffic from this AS consists of internal corporate systems, office workers, and operational endpoints supporting the company's fleet of 11 vessels and passenger services in the northern Baltic Sea region.
Notable
- All registrants for the announced prefixes agree with the announcer, consistently listing AS Tallink Grupp as the holder.
- The address inventory is finely subdivided into three distinct blocks, reflecting site-by-site segmentation typical of a large corporate estate rather than a public internet service.

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 2026-10-10, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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.
