Korea, Republic of · AI-generated

business corporate korea

CKBS-AS-KR is operated by Canon Korea Inc.

What it's used for

  • The address space carries corporate infrastructure, indicated by the netname SEJONG-KR and the registrant IRT-KRNIC-KR.
  • The AS announces 768 IPv4 addresses across 2 prefixes with 1 observed neighbour, a ratio consistent with an internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers and internal systems for Canon Korea’s printing, imaging, and business solutions operations.

Notable

  • Registrants IRT-KRNIC-KR align with the announcer CANON KOREA INC. for both announced prefixes.
  • Canon Korea Inc. was founded in 1985 as a joint venture between Lotte Group and Canon Inc.

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 2026-10-29. 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.
