Unclassified ARIN
Summary
Neburst LLC
hosting legacy
NEBUSRT is held by Neburst LLC, a small cloud/VPS and colocation provider selling Asia-Pacific-optimised virtual servers. The low AS number is not an early-internet pedigree: ARIN registered the organisation in January 2025 and the ASN a few weeks later, so this is a reissued number with a modern holder.
What it's used for
- Virtual-server hosting out of Asia-Pacific points of presence. The evidence lines up in three places at once: the netnames on its
/24s areNEBURST-TYO,NEBURST-HKGandNEBURST-SIN, the prefixes are registered to Neburst Networks at Tokyo, Hong Kong and Singapore addresses, and the reverse DNS resolves to per-PoP names such ashost-by.tyo.neburst.com.
Notable
- This is a hosting network. Addresses here are servers rented to customers, not subscriber lines — a common source of automated traffic, and a normal thing to see behind proxies and VPN endpoints.
- Its inventory is scattered
/24s inside23.128.0.0/10, roughly 2,048 addresses plus three IPv6/48s, acquired one block at a time through 2025 and 2026. That fragmentation is worth noticing because it is also the address-broker shape — but here the blocks are registered to the operator itself and carry first-party rDNS, which is exactly what a broker's inventory does not. - The customer base and the peering skew heavily toward mainland-China-optimised routes, so the addresses are US-registered while the servers are in APAC. Do not geolocate them to the registry country.

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: 443 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.
