Summary
Korea Internet & Security Agency
government registry infrastructure
DDNSKR-KR is operated by Korea Internet & Security Agency (KISA).
What it's used for
- The address space carries registry infrastructure, evidenced by netnames
KRNIC-NET-KRand registrantsIRT-KRNIC-KRacross all announced IPv4 prefixes. - The AS announces 1024 IPv4 addresses across 4 prefixes and 3 IPv6 prefixes, with only 4 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
Notable
- All RDAP registrants align with the announcer, consistently showing
IRT-KRNIC-KRfor the four IPv4 blocks. - KISA is the sub-organization of the Ministry of Science and ICT responsible for the allocation and maintenance of South Korea's IPv4 and IPv6 address space, with KRNIC operating under its umbrella.
- The inventory consists of four /24 IPv4 blocks and three /48 IPv6 blocks, all registered to the same KRNIC entity.

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: 442 networks and 1,783 prefixes, as published 2026-10-20. 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.
