Summary
Vexus Fiber
isp telecom hosting
One IPv6 allocation chopped into fifteen announcements at prefix lengths almost nobody uses, alongside 164 IPv4 prefixes.
What it's used for
- A fibre provider. 161,536 addresses across 164 IPv4 prefixes, fifteen IPv6 prefixes, and nine observed BGP neighbours.
Notable
- The IPv6 pieces run at /38, /39 and /40, sizes that sit between the round numbers registries hand out.
- Netnames carry two brands: the current one in
VEXUS-CGNT-NET-1, and an older abbreviation inNTSC,NTSC-CGNT-NET-1,NTS-ONLINE-2BLKandNTS-ONLINE-5BLK-1. - The AS handle still names the older brand, and a middle segment in several netnames names a transit provider.
- One block sits in
145.224, space administered by a different regional registry. - Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- Cutting IPv6 at odd prefix lengths is what happens when an operator treats a huge allocation like a scarce one and subdivides it by hand. There is no shortage to justify it, and each extra piece is another entry every router carries.
- Three generations of brand sit in the netnames at once, and the AS handle is stuck on the oldest, which is the usual order: routing identifiers change last.
- 164 IPv4 prefixes for one provider is a fragmentation record for this part of the table, and the addresses were clearly assembled from many small purchases rather than one allocation.

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: 442 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.
