Summary

Keski-Suomen Valokuituverkot Oy

Finland · AI-generated

ftth isp residential finnish

The AS handle KSVVNET is held by Keski-Suomen Valokuituverkot Oy.

What it's used for

  • The address space carries residential fiber-to-the-home traffic, evidenced by reverse DNS entries such as ip196-0.ksvvnet.fi and ip29-0.ksvvnet.fi.
  • The network announces 6144 IPv4 addresses across 3 prefixes with only 2 observed neighbours, a ratio indicative of an access network serving local subscribers rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs and home internet connections for customers in central Finland, specifically the Jyväskylä region.

Notable

  • Registrants for the largest prefixes (195.181.192.0/20 and 185.121.216.0/22) are listed as "KSVV Admin; Keski-Suomen Valokuituverkot Oy", while the 146.66.28.0/22 prefix is registered to "SELTIMIL TECH".
  • The address inventory is composed of three distinct IPv4 blocks, with no IPv6 prefixes currently announced 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: 440 networks and 1,773 prefixes, as published 2026-10-13. 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.
