Summary

Sakura Link Limited

Hong Kong · AI-generated

hosting transit legacy

AS9516 (SAKURALINK-AS-AP) is held by Sakura Link Limited, a Hong Kong network and hosting company. Despite the low, legacy-range AS number, APNIC records the current registration as recent — the number appears to have been recycled and re-issued rather than held continuously since the 1990s.

What it's used for

This is an IPv6-only AS in the routing table. RIS sees zero IPv4 prefixes and three IPv6 /48s, all adjacent and drawn from the same 2401:f460::/32 block: 2401:f460:2100::/48, 2401:f460:2200::/48 and 2401:f460:2300::/48. Against that tiny inventory it shows 8 observed neighbours — a ratio that tells you more than the address count does. A network with essentially no addresses of its own but a spread of BGP adjacencies is not serving end users out of this AS; it is doing interconnection. Sakura Link operates hosting infrastructure in Hong Kong and runs an exchange point there, and this AS reads as a piece of that interconnection and v6 hosting estate rather than as the company's main customer-facing network.

Notable

  • Sakura Link's principal, IPv4-carrying registration is a separate, much higher-numbered AS; AS9516 is the v6 sibling and carries none of the company's IPv4 space.
  • Zero IPv4 prefixes originated is genuinely unusual in the legacy AS range — most networks this old are IPv4-first with v6 bolted on later. Here the number is old and the deployment is new.
  • Upstreams and peers are Hong Kong hosting and transit carriers, consistent with a colocation/hosting footprint rather than an eyeball base.

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: 431 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.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
