About this network

MDE-AS is operated by Ministerio de Defensa, the Spanish Ministry of Defence.

What it's used for

• The address space carries government and military infrastructure, evidenced by the netname MDE-NETS and reverse DNS entries pointing to mde.es.
• The AS announces 512 IPv4 addresses within a single prefix (193.33.2.0/23) and maintains only 1 observed neighbour, indicating a small, isolated internal network rather than a transit or access provider.
• Traffic from this AS consists of internal communications, command and control systems, and administrative services for the Spanish armed forces.

Notable

• The registrant Ministerio de Defensa aligns directly with the AS holder and the mde.es domain in reverse DNS.
• The address inventory is compact, consisting of a single /23 block, which is typical for a specific government department's internal estate rather than a large-scale ISP.
