Summary

Seoul Metropolitan Office of Education

Korea, Republic of · AI-generated

education government korea

SENNEIS-AS-KR is operated by the Seoul Metropolitan Office of Education.

What it's used for

  • The address space carries netnames such as SEN-KR, PUBNETPLUS-KR, SERIICENTER-KR, and broadNnet-KR, indicating infrastructure for educational institutions and public networks in Seoul.
  • The AS announces 7168 IPv4 addresses across 18 prefixes with only 1 observed neighbour, a ratio that implies an access or internal network rather than a transit provider.

Notable

  • All registrants in the sample are IRT-KRNIC-KR, which aligns with the Korean National Internet Center registry, though the netnames vary across different sub-allocations.
  • The inventory consists of 18 IPv4 prefixes with no IPv6 prefixes announced, showing a purely IPv4-based estate.

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: 448 networks and 1,849 prefixes, as published 2026-10-30. 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.
