Summary

China Mobile (Guangdong)

China · AI-generated

isp mobile eyeball backbone

China Mobile Group Guangdong (CMNET-GuangDong-AP) is the Guangdong-province network of China Mobile, the world's largest mobile operator by subscribers.

What it's used for

  • Mobile data and broadband for China Mobile customers in Guangdong province, part of the nationwide CMNET backbone.

Notable

  • A very large "eyeball" network — addresses here are typically consumer mobile devices behind carrier-grade NAT, so geolocation is coarse.
  • One of China Mobile's provincial ASNs; the operator splits its enormous network across many regional autonomous systems.

Interesting

  • Guangdong is one of China's most populous and economically active provinces, making this one of the busier regional slices of China Mobile's network.

Classification and threat

Mobile Cellular carrier. Addresses are shared by many handsets via CGNAT.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

1 DROP match Announced space overlapping the DROP prefix list.

AnnouncedDROP entryRecord
120.233.56.0/21120.233.59.0/24SBL656001

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 436 networks and 1,769 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

1 IC3 indicators addresses in this network appear in FBI IC3 cybersecurity advisories.

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