Summary

SingAREN

Singapore · AI-generated

education research network

SINGAREN-GIX-IHPC-AS-AP is operated by SingAREN (Singapore Advanced Research and Education Network).

What it's used for

  • The address space carries research and education traffic, as indicated by the registrant SingAREN; IRT-SINGAREN-GIX-SG and the netname SINGAREN-GIX-AS-AP.
  • The AS announces 256 IPv4 addresses and 1 IPv6 prefix, with only 2 observed neighbours, implying a small-scale access or internal research network rather than a transit provider.

Notable

  • The registrant SingAREN aligns with the announcer, confirming the space belongs to the Singapore Advanced Research and Education Network.
  • The inventory consists of a single IPv4 prefix (103.5.240.0/24) and one IPv6 prefix (2401:c7c0:2::/48), representing a compact, dedicated allocation for the research community.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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 1,773 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.
