Summary

Zertia

Spain · AI-generated

business iot telecom spain

The AS handle ZERTIA-AS is held by Zertia Telecomunicaciones S.L.

What it's used for

  • The address space carries corporate and IoT traffic, evidenced by reverse DNS records pointing to zertia.es and registrant netnames like ES-ES-ZERTIA-20060223.
  • The network announces 8192 IPv4 addresses across 6 prefixes with only 2 observed neighbours, indicating a small, isolated corporate estate rather than a transit or large-scale access network.
  • Traffic from this AS consists of web/API endpoints and IoT device telemetry, as Zertia operates a proprietary IoT and Big Data analytics platform for real-time monitoring and industrial data analysis.

Notable

  • All registrants in the RDAP data agree with the announcer, consistently listing ZERTIA TELECOMUNICACIONES S.L. and Zertia Abuse Team.
  • The address inventory is finely subdivided into six prefixes within the 88.87.128.0/18 range, reflecting site-by-site segmentation typical of an internal corporate network.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, 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 1,772 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.
