Summary

Marina Bay Sands

Singapore · AI-generated

business hospitality corporate

MBS-SG is operated by Marina Bay Sands Pte Ltd.

What it's used for

  • The address space carries corporate infrastructure for the Marina Bay Sands resort, as indicated by the netnames MBS-SG and MBS-AS-AP and registrant Marina Bay Sands Pte Ltd.
  • The AS announces 1280 IPv4 addresses across 2 prefixes with 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or large-scale access provider.
  • Traffic from this AS consists of internal corporate systems, guest Wi-Fi, and operational endpoints for the integrated resort facility.

Notable

  • Registrants for both announced prefixes align with the announcer, listing Marina Bay Sands Pte Ltd and IRT-MBS-SG.
  • The inventory consists of two distinct IPv4 blocks: 182.16.232.0/22 and 223.255.254.0/24, with no IPv6 prefixes announced.

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: 454 networks and 1,852 prefixes, as published 2026-11-08. 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.
