- Worth noticing
- The table distinguishes official ISP information from user reports and tracks CGNAT, IPv6, static-IP access, and server rules.
Field notes
The ISP finder exposes records across 41 US home providers, with filters for state, CGNAT, IPv6, and port availability. The homepage reports 187 answers backed by 181 cited sources and labels some findings as reports, partly official, or unknown; dated entries show checks from October 16–17, 2026. A submission link invites readers to add provider-specific evidence.
