Summary

Nebula Global

United States of America · AI-generated

hosting business cloud streaming

NEBULA-GLOBAL is the AS handle for Nebula Global LLC, a network services provider.

What it's used for

  • The address space carries infrastructure for cloud and streaming services, evidenced by registrant netnames such as STARCLOUDGLOBAL-HK and STARCLOUD-GLOBAL-CGNT-NET-12.
  • The AS announces 216,320 IPv4 addresses across 130 prefixes and 10 IPv6 prefixes, while maintaining 61 observed neighbours, indicating a role focused on hosting and business connectivity rather than pure transit.

Notable

  • Registrants include StarCloudGlobal-HK, STARCLOUD GLOBAL PTE. LTD., and NTT America, Inc.; VIPAR, showing a mix of corporate entities and leased space within the announced inventory.
  • The address inventory is heavily subdivided into /19 and /20 blocks, primarily in the 154.0.0.0/8 and 206.0.0.0/8 ranges, consistent with a large-scale internal corporate or cloud estate.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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
103.179.148.0/23103.179.148.0/24SBL639191

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 454 networks and 1,847 prefixes, as published 2026-11-11. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

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