Summary
Red Eléctrica de España
utility transmission infrastructure corporate
The AS handle REE-AS is held by Red Eléctrica de España S.A.U.
What it's used for
- The address space carries internal corporate infrastructure, evidenced by the consistent netname
REEacross all available registrant records. - The inventory consists of 7 IPv4 prefixes totaling 8448 addresses, with 6 observed routing neighbours, indicating a small, self-contained corporate estate rather than a transit or access network.
- Traffic from this AS represents internal operations for Spain's electricity transmission grid operator, including control systems, office networks, and backhaul connections for grid management.
Notable
- Registrants for the available prefixes consistently identify Red Eléctrica de España S.A.U., matching the AS holder.
- The address inventory is finely subdivided into seven distinct prefixes, reflecting site-by-site segmentation typical of a large utility's internal network.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
6 upstream, 0 downstream and 6 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, 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: 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.
