Summary
Singtel ConnectPlus
isp enterprise legacy
AS9255 (CONNECTPLUS-AS) is registered to Singapore Telecommunications (Singtel) and carries the name of ConnectPlus, Singtel's managed IP-VPN and enterprise connectivity product line. It sits inside the Singtel group alongside the carrier's other autonomous systems and takes its routes through them.
What it's used for
The evidence points two ways, and both are worth stating. RIS sees 38 IPv4 prefixes carrying 25,088 addresses, 50 IPv6 prefixes, and 41 observed neighbours.
The IPv6 side reads as enterprise service: 50-odd prefixes, almost all individual /48s out of 2001:c20::, which is the classic shape of per-customer assignments handed to sites on a managed VPN. The long tail of the IPv4 table says the same thing — single /24s pulled from unrelated ranges (194.124.188.0/24, 158.155.250.0/24, 157.234.216.0/24, 103.102.235.0/24), the kind of scattered small blocks that accumulate when a carrier routes address space on behalf of business customers.
But the largest blocks tell a different story. The 151.192.0.0 /21s and the 118.201.16.0/20 resolve under singnet.com.sg with broadband-style templated names (bb151-192-16-5.singnet.com.sg). SingNet is Singtel's consumer ISP brand. So the same AS is announcing space that carries SingNet's broadband naming convention alongside what look like enterprise customer routes. The honest reading is that this is a Singtel-group AS whose inventory is mixed, and that the ConnectPlus name describes the product it was created for rather than the whole of what it now carries.
Notable
- Singtel operates several autonomous systems; AS9255 takes transit from the group's own networks rather than standing alone.
- Do not read the SingNet PTRs as making this the consumer eyeball AS, and do not read the ConnectPlus handle as making it purely enterprise. The routing table contains both.

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 1,771 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.
