Summary

Incheon Free Economic Zone

Korea, Republic of · AI-generated

government business infrastructure

The AS handle SGUC-AS-KR is held by Incheon Free Economic Zone.

What it's used for

  • The address space carries infrastructure for the Incheon Free Economic Zone Authority, with all four announced prefixes registered under the netname KREN-KR and registrant IRT-KRNIC-KR.
  • The AS announces 8192 IPv4 addresses across 4 prefixes and maintains 2 observed neighbours, indicating a limited internal network footprint rather than a large-scale access or transit provider.
  • Traffic from this AS supports the operational and business infrastructure of the Incheon Free Economic Zone, a designated Korean economic zone comprising the Songdo, Cheongna, and Yeongjong regions.

Notable

  • The registrants for all announced prefixes are IRT-KRNIC-KR with the netname KREN-KR, which aligns with the Korean registry infrastructure rather than the specific economic zone authority, suggesting the address space is allocated through the national registry.
  • The address inventory consists of four contiguous IPv4 blocks within the 223.194.0.0/16 range, specifically 223.194.208.0/20, 223.194.200.0/21, 223.194.196.0/22, and 223.194.224.0/22.

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 1,771 prefixes, as published 2026-10-15. 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.
