Summary

IWSC

Romania · AI-generated

isp residential rumania

The AS handle IWSC is held by IWSC LANSOFT DATA SRL.

What it's used for

  • The space carries residential and small business internet access, evidenced by the netname RO-INTERLAN-20181228 and reverse DNS entries pointing to iwsc.ro.
  • The network announces 1024 IPv4 addresses across 1 prefix and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small-scale access provider rather than a transit hub.
  • Traffic from this AS consists of subscriber eyeballs for local internet access services in Romania.

Notable

  • The registrant for the announced prefix is Asociatia Interlan, which differs from the AS holder IWSC LANSOFT DATA SRL, suggesting a historical association or lease arrangement.
  • The address inventory is compact, consisting of a single /22 block and a single IPv6 /29, typical of a small regional ISP.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-20, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,778 prefixes, as published 2026-10-20. 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.
