About this network

EE-CERT is operated by the Information System Authority (RIA), Estonia's national computer emergency response team.

What it's used for

• The address space carries security incident response infrastructure, evidenced by the netname EE-CERT-20110124 and reverse DNS entries like 254-141.rev.cert.ee.
• The AS announces 2048 IPv4 addresses and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, isolated network dedicated to specific operational functions rather than general transit or mass access.
• Traffic from this AS consists of security monitoring, incident coordination, and critical infrastructure support services provided by the Estonian state authority.

Notable

• Registrants align with the announcer, listing CERT NOC; Information System Authority; Abuse Contact for the primary prefix.
• The address inventory is compact, consisting of a single /21 IPv4 block and a /32 IPv6 prefix, consistent with a specialized government agency rather than a commercial ISP.
