All ISPs / AT&T Internet Air
Does AT&T Internet Air use CGNAT?
Short answer: Yes. AT&T Internet Air puts home customers behind CGNAT by default, according to AT&T Internet Air's own documentation plus customer reports. We found no way for home customers to opt out.
Can I self-host on AT&T Internet Air?
| CGNAT by default? | Yes Confidence: Medium: ISP hints or confirms part of it; the rest is customer reports. AT&T's wording is hedged ('may use CGNAT'). Customer reports say yes. AT&T's own support article says Internet Air 'may use CGNAT', and customer reports consistently say there's no public IPv4 or working port forwarding. A community thread says Internet Air for Business may still get a public IP. If you need direct remote access (port forwarding), AT&T Internet Air may use CGNAT, which can limit direct inbound connections.
