Summary

SXBCTV

China · AI-generated

isp china broadband

The AS handle SXBCTV-AP is held by SXBCTV, an Internet Service Provider.

What it's used for

  • The address space carries residential and business internet traffic, as indicated by the registrant netname SXNI across all major prefixes.
  • With 505,344 IPv4 addresses announced against only 3 observed neighbours, the ratio strongly implies an access or eyeball network rather than a transit provider.

Notable

  • All RDAP registrants for the largest prefixes are IRT-SXNI-CN with the netname SXNI, which aligns with the announcer's identity.
  • The inventory consists of 14 IPv4 prefixes and 1 IPv6 prefix, all located in China.
  • The address inventory includes a mix of large blocks like 182.80.0.0/14 and smaller subdivisions such as 59.153.4.0/23.

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: 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

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.
