Summary

Korea Expressway Corporation

Korea, Republic of · AI-generated

government infrastructure toll corporate

FREEWAY-AS-KR is operated by Korea Expressway Corporation.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by the netname HIGHWAY-KR and the registrant IRT-KRNIC-KR.
  • The AS announces a single IPv4 prefix, 180.148.180.0/22, comprising 1024 addresses, with 3 observed routing neighbours.
  • This ratio of a small, finely subdivided address estate against a low neighbour count indicates an internal corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal operations for the national expressway system, including toll collection infrastructure and administrative endpoints.

Notable

  • The registrant IRT-KRNIC-KR aligns with the announcer, Korea Expressway Corporation.
  • The address inventory consists of a single contiguous /22 block, typical of a dedicated corporate allocation.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-24, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 443 networks and 1,779 prefixes, as published 2026-10-25. 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.
