About this network

STARHUB-INTERNET is the main internet network of StarHub Ltd, one of Singapore's three major telecommunications operators.

What it's used for

• Residential broadband and cable internet across Singapore, plus business connectivity and StarHub's own services.
• Hundreds of thousands of IPv4 addresses — this is genuine eyeball space, where the addresses you see belong to consumers rather than servers.

Notable

• StarHub competes with Singtel and M1 in a small, dense, extremely well-connected market; Singapore's national fibre rollout means most of these subscribers sit on high-speed fibre rather than the cable plant StarHub started with.
• An IP in this range is a strong signal of a Singapore consumer, which is why it shows up frequently in geolocation and abuse datasets for the country.
