AS4631 UTCNET-AP
Unclassified APNIC
Summary
United Technologies Corporation (Singapore hub)
enterprise legacy
UTCNET-AP is registered to United Technologies Corporation, the US aerospace and building-systems conglomerate. The APNIC record states plainly that the number exists to give UTC's Singapore hub dual-provider internet service.
What it's used for
- Corporate connectivity for a single company site: multihoming the Singapore hub across two upstream providers so the office stays reachable if one link fails.
Notable
- A textbook enterprise AS. It announces a single /24, the minimum needed to multihome, and carries no customer traffic.
- United Technologies no longer exists in the form the registry names: it merged with Raytheon in 2020, and its Otis and Carrier businesses were spun off at the same time. The APNIC record was not updated to name a successor, so the operator behind the ASN today is not identifiable from the registry alone.

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: 453 networks and 1,854 prefixes, as published 2026-11-06. 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.
