Summary
Visionary Communications LLC
isp legacy
VISIONARY is Visionary Communications, trading as Visionary Broadband: an ISP founded in 1994 and headquartered in Gillette, Wyoming, serving fibre and fixed-wireless subscribers across Wyoming, Colorado, Montana and New Mexico. Its wholesale transport arm operates as Mammoth Networks.
What it's used for
Regional broadband access, aggregated into a single origin AS. RIS sees 37 announced IPv4 prefixes carrying about 123,392 addresses and 3 IPv6 prefixes, against 31 observed BGP neighbours — more peers than a pure enterprise but nowhere near the hundreds a wholesale carrier would show, consistent with an access network that also runs a middle-mile business and therefore hands off to a fair number of regional partners.
The reverse DNS is where this AS gets interesting: it is not one company's naming, it is a dozen. Sampled PTRs fall under mammothnetworks.com, vail.net, colorado.net, internetcolorado.net, go180.net, ptera.net, empnet.net and oregontrail.net. Those are the brands of the independent Rocky Mountain and Inland Northwest ISPs Visionary has rolled up. The blocks and their rDNS zones came along with the acquisitions and were re-originated here rather than renumbered.
Notable
The IPv4 footprint reflects that history — a dozen unrelated /19s from different eras, plus scattered /21s and /23s, rather than one contiguous allocation. Names like dslb5.internetcolorado.net and 66-201-128-5.dynamic.mammothnetworks.com mark subscriber pools; the mix of dynamic, cust and DSL naming across acquired brands is the signature of an eyeball network assembled by acquisition.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
