See the public IP your traffic is exiting through and the reverse PTR your network is announcing. Useful for ISP debugging, VPN sanity checks, and pairing with the DNS Leak Test.
The IP above is your egress; it does not reveal the recursive resolver your device asks. Run the DNS Leak Test next — it issues queries against a unique subdomain so we can see which resolver shows up on our authoritative server.
Run DNS Leak TestModern operating systems hide this behind a few abstractions (DHCP, VPN, Wi-Fi profile). The most reliable trick: query a unique subdomain we control and see which resolver IP shows up at our authoritative server. The DNS Leak Test tool does exactly this; this page reports your public IP and the reverse PTR for context.
A PTR record maps an IP address back to a hostname. ISPs and cloud providers usually publish PTR records that hint at where you’re connecting from, e.g. ip-1-2-3-4.eu-west-1.compute.amazonaws.com.
What you see here is the public IP your traffic exits through — it's the same IP every website you visit can see. To hide it, use a VPN or Tor; to test which DNS server that VPN uses, run our DNS Leak Test.
Residential ISPs often rotate IPv4 addresses with each modem reboot, and CGN (carrier-grade NAT) shares one IP between many subscribers. Mobile networks switch IPs as you move between cell towers.
