Find Your True Corporation IP Address
Your public IP is assigned by True Corporation 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.
True Corporation DNS Servers
Your router receives True Corporation 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 True Corporation 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.
True Corporation IP Ranges — AS17552
True Corporation announces its public IP ranges under ASN 17552 in the global BGP routing table, so addresses in those prefixes trace back to this network. Browse the announced prefixes on the AS17552 page, look up a single address with IP Lookup, or read what an ASN is.

How do I check if an IP address belongs to True Corporation?
Look the address up and check its ASN and organization: ranges True Corporation announces under ASN 17552 appear in the global BGP routing table. Use the HackMyIP IP Lookup for a single address, or browse the prefixes announced under AS17552 on the ASN page.
How do I find my True Corporation IP address?
Your public IP is assigned by True Corporation 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 True Corporation use?
Your router receives True Corporation 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 True Corporation 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 True Corporation 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 True Corporation whether your plan supports a static IP.
