Summary

Washington Broadband

United States of America · AI-generated

cable isp residential business

The AS handle WASHINGTON-BROADBAND is held by Washington Broadband, Inc.

What it's used for

  • The address space carries a mix of residential and business cable services, evidenced by reverse DNS entries like syn-071-093-025-000.biz.spectrum.com and 104-245-129-0.wabroadband.com.
  • With 4608 IPv4 addresses announced across 8 prefixes and 14 observed neighbours, the ratio suggests an access network providing last-mile connectivity rather than a transit provider.

Notable

  • Registrants include Charter Communications LLC for prefixes like 71.93.24.0/22 and 71.93.22.0/23, alongside Washington Broadband, Inc. for 104.245.128.0/22, indicating a complex ownership or leasing arrangement.
  • The inventory includes a single IPv6 prefix 2606:4680::/32 and a small IPv4 block 38.119.167.0/24 registered to PSINet, Inc., which does not fit the primary Washington Broadband or Charter pattern.

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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
