Korea, Republic of · AI-generated

education university seoul kr

DONGDUK-AS-KR is operated by Dongduk Women's University.

What it's used for

  • The address space carries university infrastructure, evidenced by the netname DONGDUK-NET-KR and the reverse DNS record career.dongduk.ac.kr.
  • The AS announces 2816 IPv4 addresses across 5 prefixes with only 1 observed neighbour, a ratio characteristic of a single-site access network rather than a transit provider.
  • Traffic from this AS consists of student and staff access, academic services, and institutional web endpoints for a private university in Seoul.

Notable

  • Registrants for the majority of prefixes are IRT-KRNIC-KR under the netname KORNET-KR, while the specific university block 202.20.119.0/24 uses the netname DONGDUK-NET-KR.
  • The address inventory is composed of four /22 and /24 blocks from the 210.121.0.0/16 range and one /24 from 202.20.0.0/16, indicating a consolidated allocation from the Korean National Internet Center.

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: 453 networks and 1,848 prefixes, as published 2026-11-13. 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.
