About this network

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.
