isp residential cable dsl

MULTIFI-AS is the autonomous system for JNT (Jakobstadsnejdens Telefon Ab).

What it's used for

  • The address space carries residential access traffic, evidenced by reverse DNS entries such as 3e48efff.adsl.multi.fi and 254-82.dynamonet.fi.
  • The AS announces 50432 IPv4 addresses across 5 prefixes and 2 IPv6 prefixes, while maintaining only 7 observed neighbours, a ratio indicative of an access or eyeball network rather than a transit provider.

Notable

  • Registrants for the majority of the inventory are consistent with the announcer, listing Jakobstadsnejdens Telefon Ab for the largest blocks, though smaller prefixes are registered to Ab Narpes Dynamo Net Narpio Oy and Oy Snellman Ab.
  • The address inventory is dominated by a single large /17 block, with the remaining space divided into smaller /19, /22, and /24 prefixes.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-27, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 447 networks and 1,852 prefixes, as published 2026-10-27. 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.
