Summary
Midco
residential isp midwest broadband
MIDCO-NET-DW is operated by Midco, a regional telecommunications provider headquartered in Sioux Falls, South Dakota.
What it's used for
- The address space carries static residential and business broadband connections, evidenced by reverse DNS entries such as
216-12-180-0-static.midco.netand216-12-183-255-static.midco.net. - The AS announces a single IPv4 prefix,
216.12.176.0/20, comprising 4096 addresses, with zero IPv6 prefixes. With only one observed neighbour, this configuration indicates a leaf access network rather than a transit provider.
Notable
- The RDAP registrant for the announced prefix is listed as Midcontinent Communications, which aligns with the AS holder identity.
- The company rebranded from Midcontinent Communications to Midco in 2016, a change reflected in the current corporate identity while the registry handle retains the older name.
- The inventory consists of a single contiguous /20 block, representing a compact and focused address estate for its regional service area.

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: 448 networks and 1,851 prefixes, as published 2026-11-04. 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.
