Summary
Hoshin Multimedia Center Inc.
isp residential legacy
AS9416 (MULTIMEDIA-AS-AP) is held by Hoshin Multimedia Center Inc., a Taipei-based broadband provider and one of the largest cable-and-DSL consumer ISPs in Taiwan. Its network runs on the Koos Broadband Telecom (kbtelecom.net) platform — the Koos/kbro cable group, whose franchises supply pay-TV and residential broadband across Taiwanese cities.
What it's used for
Mass-market consumer access, at real scale. RIS observes 79 IPv4 prefixes totalling 1,248,768 addresses plus one IPv6 /32 (2001:d58::/32), against only 25 observed BGP neighbours. Over a million addresses with fewer than thirty peers is the definitive eyeball signature: this network hands addresses to subscribers rather than carrying other people's traffic. The reverse DNS makes it explicit — sampled hosts resolve as host-58-114-0-5.dynamic.kbtelecom.net and host-5.0-234-182.cable.dynamic.kbtelecom.net, with dynamic, cable and static all appearing as distinct customer classes. Backbone and exchange-point gear shows up under IX.kbtelecom.net with names like TPNOC3-P68-10G5-14-GAMA, identifying Taipei NOC 10G interfaces.
Notable
- Sampled addresses in
203.133.9.0resolve todeploy.akamaitechnologies.com, meaning Akamai edge caches sit on-net inside this ASN. That is normal for an ISP of this size and is why some of its space serves CDN content rather than subscribers. - One PTR in the sample (
219-70-0-5.twt1.com.tw) points outside the kbtelecom naming, a reminder that rDNS shows what a block carries, not who holds it. - The address holdings are enormous for a non-incumbent: multiple /15s and a long list of /16s, accumulated across the cable industry's consolidation in Taiwan.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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
2 IC3 indicators addresses in this network appear in FBI IC3 cybersecurity advisories.
| Prefix | Advisory | Published |
|---|---|---|

123.252.122.7 | Chinese Government-linked Cyber Threat Actors Combine Automated and Hands-on Hacking Tools to Steal Sensitive Data | 2026-10-08 |
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
