Find Your AT&T Wireless IP Address
Your public IP is assigned by AT&T Wireless when your router or device connects, typically through DHCP or PPPoE — it is not printed anywhere on your device. The Your IP card above shows the address your current connection is using right now; for full details (location, ASN, network type, VPN detection) run the HackMyIP check or look any address up with IP Lookup. Consumer plans typically get a dynamic address that can change on reconnect or lease renewal — see static vs dynamic IP.
AT&T Wireless DNS Servers
Your router receives AT&T Wireless resolver addresses automatically over DHCP when it connects, so most customers never configure DNS at all. The exact resolver addresses vary by region and plan — check your router admin page for the values in use, or run the DNS leak test to see which resolver is answering your queries right now. Whichever resolver you use can see every domain you look up, which is why many people switch to a public resolver: see the best DNS servers compared and what your ISP can see. Some ISP-supplied routers do not allow changing DNS; in that case set it per device instead.
Does AT&T Wireless Use CGNAT?
Whether your line sits behind carrier-grade NAT depends on your plan and region, so check it yourself: compare your router WAN address with the public IP shown above. If they differ, or the WAN address falls in 100.64.0.0/10 (the shared range RFC 6598 reserves for CGNAT), you are behind CGNAT — one public IP shared by many customers, which matters for port forwarding, hosting a server, and some games. Many providers, and most mobile networks, deploy it. Classify any address with the Special-Use IP Checker or read what CGNAT is.
AT&T Wireless IP Ranges — AS7018
AT&T Wireless announces its public IP ranges under ASN 7018 in the global BGP routing table, so addresses in those prefixes trace back to this network. Browse the announced prefixes on the AS7018 page, look up a single address with IP Lookup, or read what an ASN is.

Look the address up and check its ASN and organization: ranges AT&T Wireless announces under ASN 7018 appear in the global BGP routing table. Use the HackMyIP IP Lookup for a single address, or browse the prefixes announced under AS7018 on the ASN page.
How do I find my AT&T Wireless IP address?
Your public IP is assigned by AT&T Wireless when your router or device connects, typically through DHCP or PPPoE, so it is not printed anywhere on your device. The fastest way to see it is an external check, which shows the address the rest of the internet sees. The Your IP card on this page shows the address your current connection is using right now.
What DNS servers does AT&T Wireless use?
Your router receives AT&T Wireless resolver addresses automatically over DHCP, and the exact addresses vary by region and plan, so check your router admin page for the values in use. You can also run a live DNS leak test to see which resolver is answering your queries right now, and replace the ISP resolvers with a public resolver on your router or per device.
Does AT&T Wireless use CGNAT?
That depends on your plan and region, so check your own line: compare your router WAN address with the public IP shown on this page. If they differ, or the WAN address falls between 100.64.0.0 and 100.127.255.255 (the shared range RFC 6598 reserves for carrier-grade NAT), you are behind CGNAT. Many providers, and most mobile networks, use CGNAT to share one public IP among many customers.
Why does my AT&T Wireless IP address keep changing?
Consumer ISPs typically assign dynamic public IPs with a limited lease, and address pools are reused as leases expire, so a reconnect, a router reboot, or a lease renewal can hand you a different address. If you need an address that never changes, ask AT&T Wireless whether your plan supports a static IP.
