Summary

Sejong City Office of Education

Korea, Republic of · AI-generated

education government korea

SJEDU-AS-KR is operated by Sejong City Office of Education.

What it's used for

  • The address space carries netnames broadNnet-KR and PUBNETPLUS-KR, indicating infrastructure managed by the Korean government's public network providers for educational institutions.
  • The AS announces 4,608 IPv4 addresses across 15 prefixes with only 1 observed neighbour, a ratio consistent with an access network serving a specific institutional estate rather than a transit provider.
  • Traffic from this AS consists of network connectivity for schools and administrative offices under the jurisdiction of the Sejong City Office of Education.

Notable

  • Registrants for all sampled prefixes are IRT-KRNIC-KR, which aligns with the government-owned nature of the netnames broadNnet-KR and PUBNETPLUS-KR rather than the specific education office handle.
  • The inventory is composed of multiple /24 and /23 blocks, reflecting a segmented allocation typical of a municipal or regional administrative network.

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: 447 networks and 1,843 prefixes, as published 2026-11-02. 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.
