Summary

El Corte Inglés

Spain · AI-generated

retail corporate business

ECI-AS is operated by El Corte Inglés S.A.

What it's used for

  • The address space carries corporate infrastructure for the Spanish department store chain, evidenced by the reverse DNS record pasareladepagos.elcorteingles.es (payment gateway) and netnames ES-ECI-20180129 and ES-SUPERCOR-20180912.
  • The AS announces 1792 IPv4 addresses across 3 prefixes with 3 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate systems, web services, and payment processing endpoints for the retail business.

Notable

  • Registrants align with the announcer, listing El Corte Ingles S.A. for the primary block and SUPERCOR S.A. for the secondary blocks, reflecting the corporate structure of the retail group.
  • The inventory is finely subdivided into three distinct prefixes, consistent with internal site-by-site segmentation for a large retail estate.

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
