AS10122 NETSTAR-AS-AP NETSTAR SG PTE. LTD.

NETSTAR-AS-AP is NETSTAR (SG) Pte. Ltd., a Singapore company registered in 2017. Its network is the delivery backbone for BIGO's consumer apps — the live-streaming and short-video services BIGO Live, Likee and imo. The tie is visible in the infrastructure itself: NETSTAR's own peering site is served by BIGO's static hosting, and BIGO's bigo.tv is hosted on netstartech.sg.

What it's used for

Pushing video and app traffic to users across Asia and beyond. The AS announces 225 IPv4 prefixes totalling 57,600 addresses plus 6 IPv6 prefixes — and, notably, every single announced block is a /24. That is not sloppiness. Fine-grained /24s are how a content network steers traffic per-site and per-exchange, letting each edge cluster be announced independently and withdrawn without touching the rest.

Notable

This is a content-delivery network, not a transit carrier, and the two signals together settle it. The AS is seen with 218 observed BGP neighbours — a huge peering footprint, on ports at exchanges from Singapore and Hong Kong to Frankfurt and Amsterdam — yet holds only 57,600 addresses. A wholesale carrier peers that widely because it sells transit; a content provider peers that widely because it wants to hand its own outbound traffic directly to eyeball networks and skip transit entirely. Its self-reported profile agrees: content provider, heavily outbound.

Interesting

Geolocate this space to edge PoPs, not to Singapore. An address here is a server in whichever city BIGO placed the cluster, and the same /24 pattern repeats worldwide.
