Summary
StarHub Ltd
isp legacy
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.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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 1,775 prefixes, as published 2026-10-11. 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.
