Summary
Singtel (Regional Satellite Business)
enterprise satellite legacy
SINGTEL-DVBIP-AS-AP is Singapore Telecommunications Ltd's satellite arm. The registry description is unusually explicit about its purpose: Regional Satellite Business — DVB/IP over satellite, operated from the Bukit Timah Satellite Earth Station.
What it's used for
- Carrying IP delivered over satellite. Singtel Satellite sells VSAT and SAT-IP services — DVB-S2 point-to-multipoint and dedicated SCPC links terminating at its teleports — to enterprises, broadcasters, remote land sites and ships.
- Its address blocks are registered under the netnames
SINGTELSAT("Regional Satellite Business Infrastructure") andSINGTEL SATELLITE, the latter held inside SingNet's allocations. There is essentially no public reverse DNS anywhere on the space.
Notable
- This is a Singtel ASN, but it is not Singtel's Singapore broadband or mobile network. It is a distinct satellite business, and its space carries no subscriber-style addressing.
- Geolocation is the real trap here. The registry says Singapore because that is where the teleport and the earth station are. The users of these addresses are wherever the satellite footprint reaches: an oil rig, a mining camp, a remote island site, or a vessel in the middle of the Asia-Pacific. Placing this space in Singapore on a map describes the ground station, not the customer.
- Treat it as enterprise and carrier connectivity rather than consumer access.
Interesting
- Satellite IP address space is one of the few categories where geolocation is not merely imprecise but structurally misleading. A single
/24behind a shared DVB-S2 carrier can host terminals thousands of kilometres apart, all of them egressing through one teleport in Singapore.

Reputation
Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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: 442 networks and 1,781 prefixes, as published 2026-10-16. 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.
