What it's used for
- The address space carries residential and business cable and fiber services, evidenced by netnames such as
WAVE-NET-24-35-64-0-19,CONDOINTERNET-SEA-3, andASTOUND-ARIN-2. - The AS announces 88,576 IPv4 addresses across 52 prefixes and 4 IPv6 prefixes, while maintaining only 1 observed neighbour, a ratio characteristic of an access network serving end-users rather than a transit provider.
- Traffic from this AS consists of subscriber eyeballs for cable TV, broadband internet, and phone services in the Pacific Northwest and other US markets.
Notable
- All registrants in the sample agree with the announcer, consistently listing Wave Broadband.
- Wave Broadband was acquired by TPG Capital and subsequently combined with Astound Broadband, RCN, and other entities to form the Astound Broadband brand.
- The inventory includes legacy netnames from Astound and Condo Internet, reflecting the consolidation of multiple cable operators under the Wave Broadband umbrella.

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 2026-11-04. 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.
