Unclassified RIPE
Summary
TS-Yhtyma
business publishing telecom
TS-YHTYMA is held by TS-Yhtyma Oy.
What it's used for
- The address space carries legacy infrastructure, evidenced by netnames
FI-SONERA-19910731andTURUN-SANOMAT-8. - The AS announces 768 IPv4 addresses across 2 prefixes with 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or large access provider.
- Traffic from this AS consists of corporate endpoints for a Finnish communications and publishing group, supporting its editorial, printing, and telecommunications operations.
Notable
- Registrants for the announced prefixes are listed as Telia Finland Oyj and Registry Telia Finland, which aligns with the historical ownership of the space prior to the current holder's acquisition or lease.
- The address inventory is small and fragmented, consisting of two distinct IPv4 blocks with no IPv6 prefixes in the inventory.

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
