Summary

Department of Education, Hsinchu City

Taiwan, Province of China · AI-generated

education government research

AS18043 is operated by the Department of Education, Hsinchu City.

What it's used for

  • The address space carries educational and research traffic, as indicated by the netname HCCG_HCEB and the registrant IRT-HCCG_HCEB-TW.
  • The AS announces 512 IPv4 addresses within a single prefix (144.79.66.0/23) and one IPv6 prefix (2402:3ce0::/32), with only 1 observed neighbour, implying a small, self-contained institutional network rather than a transit provider.

Notable

  • The RDAP registrant TWNIC ROLE-HCCG_HCEB aligns with the registry holder "Department of Education, Hsinchu City," confirming the space belongs to the Hsinchu City Government's educational division.
  • The inventory consists of a single contiguous IPv4 block and one IPv6 prefix, typical of a municipal or university network managing its own internal addressing.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
