Summary

Korea Data Telecommunication

Korea, Republic of · AI-generated

business korea datacenter

KDT-AS-KR is operated by Korea Data Telecommunication Co., Ltd.

What it's used for

  • The address space carries datacenter and infrastructure traffic, evidenced by the consistent netname KDTIDC-KR across all sampled prefixes.
  • The AS announces 31,488 IPv4 addresses across 78 prefixes with only 1 observed neighbour, indicating a dedicated corporate or datacenter estate rather than a transit or access network.
  • Traffic from this AS consists of datacenter workloads and enterprise services hosted within Korea Data Telecommunication's facilities.

Notable

  • All registrants are IRT-KRNIC-KR with netname KDTIDC-KR, which aligns directly with the announcer's identity as Korea Data Telecommunication Co., Ltd.
  • The inventory is composed of 78 IPv4 prefixes with no IPv6 announcements, showing a purely IPv4-based address allocation.

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
