Summary
Conterra
business broadband regional
DWL-MAIN is operated by Conterra, a regional broadband provider in the United States.
What it's used for
- The address space carries static IP assignments for customer premises, evidenced by reverse DNS records such as
static-139-180-40-0.conterra.comand netnames likeCUBLandCONTERRA. - With 67,584 IPv4 addresses announced across 50 prefixes and 76 observed neighbours, the network functions as an access provider connecting end-users to the internet rather than a transit carrier.
Notable
- Registrants are predominantly Conterra, with some blocks registered to Network Communications and Texas State Technical College Sweetwater, indicating historical acquisitions or leased space.
- Conterra is also known as Conterra Ultra Broadband and Detel Wireless, reflecting its evolution from a wireless operator to a fixed broadband provider.
- The inventory includes a mix of /19, /20, and /21 prefixes, with a significant portion of the space allocated to static customer addresses.

Reputation
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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
