Summary

Greek School Network (CTI "Diophantus")

Greece · AI-generated

education government legacy

GR-EDUNET is held by the Computer Technology Institute and Press "Diophantus" (CTI), the Greek public research and technology body that operates the Panhellenic School Network — the national network connecting Greece's primary and secondary schools.

What it's used for

  • About 78,000 addresses across ten prefixes (large blocks in 81.186.0.0/16 and 194.63.0.0/16), plus IPv6 from the Greek research network's 2001:648::/32.
  • Reverse DNS is uniformly on the school-network domain: names like srv-4dim-chaid.att.sch.gr and clnt-1dim-iliou.att.sch.gr — servers and client machines at individual named schools, with the regional label (att for Attica) in the zone.
  • The naming decodes to Greek school types: dim for dimotiko (primary), gym for gymnasio, sek for vocational schools.

Notable

  • Addresses here are school premises, not homes and not a commercial ISP. A hit is a classroom, a school server or a school's administrative machine.
  • CTI "Diophantus" is a state body under the Ministry of Education, so this sits at the education/government boundary; it is carded as education because the addresses are on school sites.
  • Distinct from GRNET, the Greek national research and education network that serves universities.

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: 442 networks and 1,779 prefixes, as published 2026-10-23. 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.
