Summary
Simba Telecom
isp legacy
Autonomous System 4817 (STPL-SG-AP) is held by Simba Telecom Pte Ltd, a Singaporean mobile and broadband operator.
What it's used for
- Retail telecoms in Singapore: mobile service on Simba's own 4G/5G network, and fixed home broadband.
Notable
- A consumer eyeball network — the address space serves subscribers, not servers. As with most mobile carriers, the announced IPv4 pool is small relative to the subscriber count because handsets sit behind carrier-grade NAT.
- Simba is the operator formerly branded TPG Telecom in Singapore, which entered the market as the country's fourth mobile network before rebranding in 2022; the APNIC record for this AS was updated at the same time. It is separate from TPG Telecom's Australian business.

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: 436 networks and 1,769 prefixes, as published 2026-10-13. 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.
