Unclassified Spamhaus ASN-DROP RIPE
Summary
Airu Limited
business hk leased
The AS handle AIRULIMITED is held by Airu Limited.
What it's used for
- The address space carries a mix of legacy corporate and APNIC allocations, with netnames including
CORPCOMM-BLK,APNIC-AP,VOYAGER98,LAIDLAWPSG, andMBC-JP. - The AS announces 17920 IPv4 addresses across 15 prefixes, all located in Hong Kong, while maintaining only 6 observed routing neighbours.
- This high address-to-neighbour ratio indicates an access or internal corporate network rather than a transit provider, consistent with a business entity managing specific site or service allocations.
Notable
- Registrants for the largest prefixes include Corporate Communications, Inc., APNIC Hostmaster, CoreComm Internet Services Inc, Laidlaw Passenger Services Group, and mediatti broadband communications, which differ from the AS holder Airu Limited.
- The inventory consists of 15 distinct IPv4 prefixes with no IPv6 announcements, showing a fragmented address estate drawn from multiple original registrants.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 449 networks and 1,846 prefixes, as published 2026-11-03. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
