Summary
Shenzhen Information and Network Center
business china network
SZINC-AS-AP is operated by Shenzhen Information and Network Center.
What it's used for
- The address space carries the netname
SZNETacross all eight announced IPv4 prefixes, indicating a dedicated network infrastructure for the Shenzhen region. - The AS announces 16,384 IPv4 addresses across 8 prefixes with only 1 observed neighbour, a ratio that suggests an internal or access-oriented network rather than a transit provider.
Notable
- All registrants are listed as
IRT-CNNIC-CN, which aligns with the Chinese National Internet Center (CNNIC) managing the address space for this local operator. - The inventory consists of one /19 block and seven smaller blocks (two /22s and five /23s) within the 203.175.128.0/19 range, showing a finely subdivided corporate or municipal estate.

Reputation
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: 442 networks and 1,784 prefixes, as published 2026-10-19. 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.
