Summary
StylenTech LLC
hosting legacy
STYLENTECH is StylenTech LLC, a small hosting operator whose public brand is StylenHost — "cloud based hosting, server and storage solutions" plus a software-licensing product. The low AS number is misleading: ARIN's record shows AS11721 was registered to StylenTech in April 2023, so this is a recycled number on a modern network, not an early-internet allocation.
What it's used for
RIS sees three /24s — 768 IPv4 addresses — and five IPv6 /48s, against two observed neighbours. Two upstreams and no peering fabric is a single-homed-plus-backup hosting shop, and the address count says the same: this is server space, not access space, because 768 addresses cannot carry an eyeball network but comfortably carry a few racks of VMs. The ARIN network handles say what the space is for outright — NET-STYLENHOST-V4-3 on the 155.103.216.0/23 pair and NET-STYLENTECH-V4-1 on 23.151.8.0/24.
All three IPv4 prefixes are registered in ARIN directly to StylenTech LLC. Self-registered space with the operator's own brand in the netname is what separates a real (if small) hosting company from address-leasing dressed up as one, and that is the reason this one is called hosting rather than held out.
Notable
Two details are worth recording rather than over-reading. The IPv6 spans two RIRs at once — three 2602:fa8a:…::/48s out of ARIN space alongside 2a0f:9400:7384::/48 and 2a0b:b87:ff15::/48 out of RIPE space — and the ARIN org address, Suite 27060 at 30 N Gould St in Sheridan, Wyoming, is a registered-agent mail-forwarding address rather than a place with servers in it. Neither is damning on its own for a small hosting provider, but the pair is the reason the confidence here is not high.
Interesting
The sampled reverse DNS on 23.151.8.0/24 comes back as static.5.8.151.23.example.com — a PTR generator whose template was never filled in, still pointing at RFC 2606's reserved documentation domain.

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 1,771 prefixes, as published 2026-10-15. 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.
