Does AT&T Internet Air give you a public IP?

Short answer: Usually no. AT&T's own support article says Internet Air "may use CGNAT," which can limit direct inbound connections. Customer reports consistently say there's no public IPv4 or working port forwarding on residential Internet Air. We found no residential opt-out.

Does it use CGNAT by default?

Yes in practice. AT&T's wording is hedged ("may use"), but the outcome matches CGNAT.

On the Connect a security camera support article, AT&T writes that if you need direct remote access (port forwarding), Internet Air may use CGNAT, which can limit direct inbound connections, and points people at cloud-connected cameras instead.

Customer reports say residential lines don't get a unique public IPv4 and can't port-forward (customer report, customer report). See the AT&T Internet Air ISP page for every cited source.

Official path to a public IPv4

No residential opt-out found. AT&T's High Speed Internet terms say static IPs are not available on its "Fixed Wireless Internet Service" (whether that section fully covers Internet Air isn't confirmed on the page we checked). Customer reports say only Internet Air for Business may still get a public IP in some cases. Public static IP attachments we found are for other AT&T mobility / private-connection products, not residential Internet Air.

What about IPv6?

Not yet verified from a citable AT&T page for Internet Air. If the checker shows a public IPv6, inbound over IPv6 may still work when both ends have IPv6. That doesn't replace a public IPv4 behind CGNAT.

How to confirm on your line

1. Follow how to tell if you're behind CGNAT.
2. A WAN address in 100.64.0.0/10 is the shared CGNAT range (explainer).
