cooperative residential rural dsl

WWTC-247-01 is the autonomous system for West Wisconsin Telcom Cooperative, Inc.

What it's used for

  • The address space carries residential DSL and dynamic host services, evidenced by reverse DNS entries such as elk-calix-dhcp-2-253.dsl.wwt.net and 173.245.132-0.wwt.net.
  • The AS announces 12,288 IPv4 addresses across 2 prefixes while maintaining only 1 observed neighbour, a ratio that indicates a local access network serving end-users rather than a transit provider.

Notable

  • Both registrants in the RDAP data, associated with netnames WWTC-1 and WWTC-2, match the registry holder West Wisconsin Telcom Cooperative, Inc.
  • The inventory consists of two distinct IPv4 blocks, 216.222.160.0/19 and 173.245.128.0/20, with no IPv6 prefixes currently announced.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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 2026-11-03. 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.
