AS11183 MHTC-NET

MHTC-NET belongs to Mount Horeb Telephone Company, a rural incumbent telephone company in Mount Horeb, Wisconsin that also sells broadband under the MHTC brand. The AS carries its subscriber network.

What it's used for

Residential and small-business broadband for a rural Wisconsin service area. RIS sees 21 IPv4 prefixes and roughly 12,288 addresses, no IPv6, and only four BGP neighbours — the profile of an eyeball network with a couple of transit providers, not a carrier.

Reverse DNS is unusually explicit about what the space carries. Almost every sampled address falls under mhtc.net in patterns like mthb-216-246-182-5.pppoe.dyn.mhtc.net, mthb-216-246-176-5.pppoe.sta.mhtc.net and mthb-216-180-198-5.isg.dyn.mhtc.net: a town prefix (mthb for Mount Horeb), the access method (PPPoE, or isg for the intelligent-services-gateway style session pool), and a dynamic/static marker. Those are customer sessions. The only non-subscriber name in the sample is mhcore-nrp2-gw.mhtc.net, a core gateway.

Notable

Every announced prefix in the pack is registered to MHTC's own ARIN handles (MHTC-1, MHTC-2), so the address space is genuinely the telco's rather than leased in from third parties.

The inventory is fragmented — a /19, a /20, and a long tail of /24s deaggregated out of those same supernets, which is a common (if untidy) traffic-engineering habit at small ILECs.
