Summary

Japan · AI-generated

government japan public-sector

KYOTO-PREF is the autonomous system for the Kyoto Prefectural Government.

What it's used for

  • The address space carries government infrastructure, indicated by the netname KYOTOFU-NET-CIDR-BLK-JP and the registrant Japan Network Information Center; IRT-JPNIC-JP.
  • The AS announces 256 IPv4 addresses across 1 prefix (202.34.14.0/24) and maintains 4 observed neighbours, a ratio consistent with a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal communications and services for the administrative offices of Kyoto Prefecture, a regional government entity in Japan.

Notable

  • The RDAP registrant for the announced prefix is Japan Network Information Center; IRT-JPNIC-JP, which aligns with the AS holder KYOTO Prefectural Government as the space is allocated through the national registry.
  • The address inventory is a single /24 block, representing a compact and unified estate for the prefectural government's digital operations.

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: 436 networks and 1,771 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.
