Unclassified ARIN
Summary
NetWest Online, Inc.
isp hosting legacy
NWOL-AS is NetWest Online, Inc. of 5000 E. University Blvd, Odessa, Texas (ARIN org NWOI) — a West Texas / Permian Basin internet provider that started as a dial-up ISP in the mid-1990s and now sells fixed wireless, fibre, business connectivity and colocation across the Odessa–Midland area.
What it's used for
Regional access and hosting for one operator. RIS observes four IPv4 prefixes / 8,192 addresses, one IPv6 /32 (2605:7100::/32), and two observed neighbours. Two neighbours against 8k addresses is a dual-homed edge network serving its own customers, not a carrier reselling transit.
All four prefixes are contiguous /21s out of 209.240.160.0 and are registered to NetWest's own ARIN networks (NWOL-BLK1, NWOL-CORE-ROUT, 4A-NETWEST-NETWRK). Self-registered space announced by its own holder — none of the multi-registrant, multi-RIR scatter that marks an IP-leasing operation.
Notable
The reverse DNS shows two distinct populations sharing one AS. Most addresses wear generic per-IP names under the operator's own domains (209-240-176-5.netwest.com, 209-240-172-5.nwol.net) — subscriber and infrastructure addressing. But at least one sampled address answers with a customer's own hostname (mcmelegantebeaumont.com), which is what a hosted or colocated web site looks like. A small ISP that also runs a data centre routinely mixes access pools and hosting in the same block.
Interesting
The IPv6 /32 is a notably generous allocation relative to the 8,192 IPv4 addresses — the standard minimum ARIN hands an ISP, and a reminder that IPv6 sizing says nothing about subscriber count.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation
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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
