Summary

Postal Savings Bank of China

China · AI-generated

business finance corporate

PSBCNET is operated by Postal Savings Bank of China.

What it's used for

  • The space carries corporate infrastructure for a major Chinese retail bank, identified by the netname PSBCNET and registrant IRT-PSBCNET-CN.
  • The AS announces 1024 IPv4 addresses within a single /22 prefix and 4 IPv6 prefixes, while maintaining 7 observed neighbours.
  • Traffic from this network consists of internal corporate systems, branch backhaul, and office worker connectivity for a financial institution with approximately 40,000 outlets.

Notable

  • The registrant IRT-PSBCNET-CN and netname PSBCNET align directly with the AS handle and the holder's identity.
  • The address inventory is compact, consisting of one IPv4 block and four IPv6 /48 prefixes, consistent with a segmented internal corporate estate rather than a public access network.

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.
