Summary
SingNet
isp legacy
SINGNET is the internet service provider arm of Singtel, Singapore's incumbent telecommunications operator, and one of the country's largest consumer and business ISPs.
What it's used for
- Retail internet access in Singapore: residential broadband, business connectivity, and the associated ISP services (mail, DNS, customer platforms).
- Announces a large legacy IPv4 footprint — hundreds of thousands of addresses — most of it eyeball space handed out to subscribers.
Notable
- This is eyeball address space: traffic seen from here is overwhelmingly end users on home and business broadband in Singapore, so it is a common source for consumer web and streaming traffic.
- SingNet was one of Singapore's first commercial internet providers, and the low AS number reflects how early the country's national operator got online.
Interesting
- The ASN is registered with ARIN rather than APNIC. That is a legacy artifact: SingNet's resources predate APNIC's takeover of the Asia-Pacific region, and the records simply stayed where they were originally created.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
6 upstream, 86 downstream and 116 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-10, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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.
