About this network

AS9729 (IS-AP) is held by iAdvantage Limited, the data centre arm of SUNeVision Holdings (SEHK: 1686), itself part of the Sun Hung Kai Properties group. iAdvantage is one of Hong Kong's largest carrier-neutral colocation operators, best known for the MEGA-i / MEGA Campus facilities.

What it's used for

This is a colocation and managed-services network. RIS shows 156 IPv4 prefixes covering about 84,992 addresses, plus a single IPv6 /32 (2403:2400::/32), announced to 18 observed neighbours. The address space is anchored by two large aggregates — 210.184.128.0/17 and 203.194.128.0/17 — which are then deaggregated into a long tail of /20s down to /24s. That pattern is exactly what a data centre operator produces: it holds big legacy blocks and hands out small, individually-routed slices to colocation and managed-hosting tenants, announcing the more-specifics alongside the covering aggregate. The neighbour count matters here too. Eighteen peers is far too few for a wholesale carrier and far too many for a single enterprise; it is the profile of a facility that buys transit from several Hong Kong carriers and peers at the local exchange so its tenants get diverse, low-latency reach.

Notable

• iAdvantage's value proposition is interconnection density rather than IP transit, so the AS itself is deliberately modest in peering terms while the buildings behind it carry many other networks' ASNs.
• The address space is legacy APNIC allocation from Hong Kong's early commercial internet, which is why the aggregates are unusually large relative to the operator's size today.
• Card the facility network, not the property group: this AS describes iAdvantage's own routed estate, not SUNeVision's or Sun Hung Kai's wider business.
