isp residential regional cable

ROUTER12 is operated by Router12 Networks LLC.

What it's used for

  • The address space carries residential and business subscriber traffic, evidenced by reverse DNS entries such as dynamic.router12.net and static.router12.net, and netnames like ROUTER12-NETWORKS-CGN-01.
  • The AS announces 1280 IPv4 addresses across 4 prefixes and maintains 8 observed neighbours, a ratio consistent with a regional access provider rather than a transit carrier.
  • Traffic from this AS consists of subscriber eyeballs and local business endpoints for a cable/DSL ISP serving the Mason City, Iowa area.

Notable

  • All registrants for the announced prefixes are listed as Router12 Networks LLC, matching the AS holder.
  • The inventory is composed of four distinct IPv4 blocks, including a /23 and three /24s, with no IPv6 prefixes announced.

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: 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.
