Summary

Maxisat

Finland · AI-generated

cable residential isp finnish

MAXISAT-AS is operated by Maxisat Oy, a Finnish cable television and internet service provider based in Espoo.

What it's used for

  • The address space carries residential and business customer traffic, evidenced by reverse DNS entries pointing to rev.maxisat.fi and netnames such as FI-MAXISAT-20040217 and MAXISAT-DIR.
  • The AS announces 8,192 IPv4 addresses across 6 prefixes, with a single observed neighbour, indicating a leaf access network rather than a transit provider.
  • Traffic consists of subscriber internet access and cable TV services for Maxisat's customer base in Finland.

Notable

  • Registrants for all announced prefixes are consistent with the announcer, listing Maxisat Oy or Abuse-C Role under netnames like MAXISAT-DIR.
  • Maxisat is 54% privately owned and 46% owned by HTV (Helsinki Television), a major Finnish cable TV operator.
  • The inventory consists of a contiguous block within 83.216.0.0/16, subdivided into six smaller prefixes.

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: 442 networks and 1,784 prefixes, as published 2026-10-19. 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.
