AS6500 NEXUS-22-6500 - Nexusguard, Inc
Unclassified ARIN
Summary
Nexusguard, Inc
hosting legacy
NEXUS-22-6500 belongs to Nexusguard, a DDoS mitigation and traffic-scrubbing provider that sells attack protection to communications service providers and enterprises. The low AS number is not an early-internet artifact: ARIN registered it to Nexusguard in December 2015.
What it's used for
- Security infrastructure rather than general connectivity. The AS originates a single ARIN-allocated
/24(netnameNXG-US), consistent with scrubbing-centre and service addressing rather than a customer-hosting footprint.
Notable
- Nexusguard's US entity is registered in San Francisco, but the company's operations are substantially Asia-Pacific. Treat the ARIN country as a registration fact, not a statement about where the traffic is handled.
- Both the organisation record and the ASN record date to 2015, which is the pairing that actually establishes a reissue. A modern org record alone would not.
Interesting
- AS6500 sits immediately below a run of genuine mid-1990s ARIN allocations (AS6501 onward), which is a useful reminder that adjacency in AS-number space says nothing about allocation date.

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: 448 networks and 1,851 prefixes, as published 2026-11-03. 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.
