Summary

hosting legacy
SUNNYVISION is a Hong Kong hosting provider and data centre operator, in business since 1998.
What it's used for
- Dedicated servers, VPS, cloud servers, colocation, and managed hosting out of Hong Kong facilities.
- Hosting customers who specifically want a Hong Kong presence with good connectivity into mainland China.
Notable
- This is server address space, not eyeball space: expect websites, mail, and customer-run machines rather than home broadband users.
- SunnyVision also operates AS38478, which carries a larger share of its hosted customer traffic.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 442 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.
