isp residential cable dsl

MEGATUUTTI is operated by S1 Networks Oy, the corporate entity behind the WelcomNet brand.

What it's used for

  • The address space carries residential broadband traffic, evidenced by reverse DNS entries such as 93-90-55-255.welcomnet.fi and mail.arti.fi.
  • The network announces a single IPv4 prefix, 93.90.48.0/20, comprising 4096 addresses, and maintains 2 observed routing neighbours.
  • This ratio of address space to peering partners indicates an access network providing cable and DSL services to end-users in Finland.

Notable

  • The RDAP registrant for the announced prefix is S1 Networks Oy, which aligns with the AS holder Megatuutti S1 Networks Oy.
  • The operator is identified in peering databases as EuroQuest, also known as WelcomNet, operating as a regional cable and DSL ISP.
  • The inventory consists of a single contiguous /20 block with no announced IPv6 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 1,772 prefixes, as published 2026-10-15. 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.
