Summary

Huashu media&Network Limited

China · AI-generated

media business china

WASUHZ is the AS handle for Huashu media&Network Limited.

What it's used for

  • The address space is primarily registered under the netname WASUHZ, with smaller blocks under ZJWSBTVNET, indicating a media or broadcasting network estate.
  • The AS announces 530432 IPv4 addresses across 11 prefixes and 11 IPv6 prefixes, while maintaining only 3 observed neighbours, a ratio that suggests an access or internal corporate network rather than a transit provider.

Notable

  • Registrants for the majority of prefixes are IRT-WASUHZ-CN, consistent with the announcer, while 43.225.76.0/22 and 103.17.228.0/22 are registered to IRT-ZJWSBTVNET-CN.
  • The inventory includes a large block 113.214.0.0/15 registered to APNIC Hostmaster with netname APNIC-AP, which differs from the primary WASUHZ netname seen in other prefixes.
  • The address inventory is dominated by large /15 and /16 blocks, with several smaller /22 allocations, reflecting a mixed structure of legacy and newer allocations.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, 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: 440 networks and 1,773 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.
