isp legacy

WERCS-NET is Mountain West Technologies Corporation, an independent Wyoming internet and phone provider headquartered in Casper. RIS observes 11 IPv4 prefixes covering 9,984 addresses, a single IPv6 /32 (2607:fe98::/32), and 17 neighbours.

What it's used for

This is a regional access network, and the reverse DNS says so plainly. Sampled PTRs land on CUST-176-5.mwtn.net, PPPoE-53-5.MWTN.NET, and city-tagged names such as UNUSED.CHEYENNE.MWTN.NET and CY-TRAN-75-5.mwtn.net. Customer-numbered hostnames and PPPoE session names are the signature of subscriber access rather than server hosting: the address is handed to a home or small-business circuit as it comes online. The company sells fibre and fixed wireless across Casper, Cheyenne, Wheatland, Torrington and a string of smaller Wyoming towns, and the routed space is what those subscribers sit behind.

Notable

The AS carries several older brands alongside the current one. UNUSED.WYONET.NET, pier64.net and millect.net all appear in the same address space, which is the usual fingerprint of a rural ISP that has absorbed neighbouring operators and kept their reverse-DNS zones intact rather than renumbering customers.

Interesting

Seventeen neighbours against roughly ten thousand addresses is a well-connected small ISP, not a wholesale carrier. It buys and peers more broadly than its size suggests, which is typical for an operator in a sparsely populated state where transit is expensive and route diversity is worth paying for.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
