Summary

INESC TEC

Portugal · AI-generated

research education business

The AS handle INESCTEC is held by INESC TEC - Instituto De Engenharia De Sistemas E Computadores, Tecnologia E Ciencia.

What it's used for

  • The address space carries research and institutional infrastructure, evidenced by netnames such as INESCP-PTCCFCUL, INESCP-NET, INESC-SMALL, and INESCP-NET1.
  • The AS announces 2816 IPv4 addresses across 4 prefixes with only 1 observed neighbour, indicating a small, self-contained research network rather than a transit or large-scale access provider.

Notable

  • All registrants align with the announcer, consistently identifying INESC TEC or its predecessor entities like INESC-ID.
  • The address inventory is finely subdivided into four distinct blocks, reflecting internal segmentation for different departments or projects within the institute.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, 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: 446 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.
