Summary

Eurotux Informatica SA

Portugal · AI-generated

business cloud pt

EUROTUX is operated by Eurotux Informatica SA.

What it's used for

  • The address space carries corporate and cloud infrastructure, evidenced by netnames PT-EUROTUX-CLOUD and PT-EUROTUX, with a reverse DNS record pointing to enewsletter.pt.
  • The AS announces 1792 IPv4 addresses and 2 IPv6 prefixes, maintaining 16 observed neighbours; this ratio indicates a business network with moderate peering rather than a large access or transit provider.
  • Traffic from this AS consists of web endpoints, cloud services, and corporate communications for the Eurotux organization.

Notable

  • Registrants for the majority of prefixes align with the announcer, specifically Eurotux Informatica SA, while the 154.53.194.0/24 block is registered to Cogent Communications, LLC.
  • The inventory includes a mix of Eurotux-owned blocks and a Cogent-registered prefix, suggesting a combination of owned infrastructure and leased or transit-related address space.

Reputation

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: 443 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.
