Summary
Unlimited Net, LLC
hosting isp legacy
UNLIMITEDNET is Unlimited Net, LLC, a small Indiana operator (ARIN org UNL-9, PO Box in Elizabethtown; offices in Columbus, Indiana) that sells server hosting, rural fixed-wireless access, VoIP and, more recently, IP transit.
What it's used for
- A modest, mixed network: RIS sees two IPv4 prefixes totalling 2,560 addresses plus three IPv6 prefixes, against six observed neighbours. Six neighbours is more than a single-homed enterprise and far short of a carrier, which fits a regional shop that both buys transit and resells a little of it.
- The main block,
198.134.104.0/21, is registered in ARIN to Unlimited Net itself and carries first-party reverse DNS (198-134-104-5.rev.unlimitednet.us). Self-registered space with self-branded rDNS is the signature of a real operator running its own estate.
Notable
- The second block,
168.81.218.0/23, is an outlier: it is registered through AFRINIC to AECI Information Services (Pty) Ltd, a South African company with no visible relationship to an Indiana ISP. One transferred or leased legacy/23announced alongside self-registered space is unremarkable in itself, but the registrant genuinely does not match the announcer, and that is worth knowing before geolocating anything inside it. - Both a hosting provider and a wireless access provider live behind this one AS number, so an address here can be a customer server or a rural subscriber. Treat per-prefix intent as unresolved rather than assuming either.
Interesting
- ARIN dates the ASN to 2012, well after the number range itself was first issued. A five-digit AS number here says nothing about the network's age.

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 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
