Summary
HKCOLO
hosting colocation business
GLOBAL-TRANSIT-AS-HKCOLO-AP is operated by HKCOLO ltd., a Hong Kong-based internet service provider and colocation facility.
What it's used for
- The address space carries infrastructure for colocation and data center services, evidenced by the consistent
HKCOLOnetname across the majority of announced prefixes. - The AS announces 4,608 IPv4 addresses across 7 prefixes and 1 IPv6 prefix, while maintaining 11 observed routing neighbours; this ratio of address space to peering partners is consistent with a hosting or colocation provider rather than a large-scale residential access network.
Notable
- Registrants for the primary prefixes (202.122.96.0/21, 202.122.104.0/22, 202.122.108.0/23, 112.213.64.0/24, 112.213.69.0/24, and 112.213.79.0/24) are listed as
hkcolo limitedunder theIRT-HKCOLO-HKhandle, aligning with the AS holder. - The inventory consists of a mix of /21, /22, /23, and /24 blocks in the 202.122.0.0/16 and 112.213.0.0/16 ranges, along with a single /32 IPv6 prefix.

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: 440 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.
