Summary

KEPCO

Korea, Republic of · AI-generated

utility corporate infrastructure

KEPRI-AS-KR is operated by KEPCO (Korea Electric Power Corporation).

What it's used for

  • The address space carries corporate infrastructure for the national power utility, evidenced by netnames KEPCORC-NET-KR and SEJONG-KR.
  • The AS announces 69,376 IPv4 addresses across 13 prefixes with only 2 observed neighbours, indicating a large internal corporate estate with minimal external peering.

Notable

  • Registrants are consistent with the announcer, with all prefixes registered under IRT-KRNIC-KR.
  • The inventory is dominated by the 168.78.0.0/17 block and its subdivisions, alongside smaller allocations in 210.109.0.0/16 and 203.0.0.0/8.

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 1,773 prefixes, as published 2026-10-13. 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.
