About this network

BANCOESPANAAS is operated by Banco de España, the central bank of Spain.

What it's used for

• The address space carries internal banking infrastructure, evidenced by netnames ES-BDE-20070326 and BANCOESPANA associated with the registrant Banco de España.
• The AS announces 1280 IPv4 addresses across 2 prefixes and 2 IPv6 prefixes, with only 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.

Notable

• Registrants align with the announcer for the primary block, while the secondary block 217.124.152.0/24 lists NEMESYS ABUSE TEAM as the registrant, suggesting a specific operational or abuse-handling segment within the estate.
• The inventory consists of two distinct IPv4 blocks and two IPv6 prefixes, reflecting a finely subdivided internal corporate estate typical of a central bank's segregated network architecture.
