Summary
China Unicom Guangdong
residential mobile telecom china
CHINA169-GZ is the autonomous system for China Unicom in Guangdong province.
What it's used for
- The address space carries residential and mobile traffic for the Guangdong region, evidenced by netnames such as
UNICOM-GDandUNICOM-GDDG. - With 2,657,024 IPv4 addresses announced across 487 prefixes and only 3 observed neighbours, the high address-to-neighbour ratio indicates a large access network rather than a transit provider.
Notable
- Registrants are consistent with the announcer, primarily
IRT-CU-CNfor theUNICOM-GDnetnames, with one prefix registered toCNCGROUP GD. - The inventory includes a mix of /15, /16, and /17 blocks, including large allocations like
27.42.0.0/15and58.252.0.0/15, alongside 3,441 IPv6 prefixes.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-10, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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.
1 DROP match Announced space overlapping the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
