About this network

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.
