IP Lookup (What is my IP)
Find your public IP — or look up any IP — for city, country, ASN, ISP, and reverse DNS.

Which address does the tool show as yours?
When the page opens, the OneClickUse server reads the address your connection arrived from and sends it to a separate IP information service, which returns the location and network details. That is your public address, the one websites see, and with a VPN or proxy switched on it is the VPN's exit address. Typing an IP and clicking Look up sends that address the same way, and My IP switches back to your own.
On a network with both IPv4 and IPv6, the result shows whichever protocol your browser used to reach the site, often IPv6. Many devices rotate temporary IPv6 addresses for privacy, so the address can change from one day to the next. IPv6 addresses are often shortened with ::, which stands for one run of zero groups, so 2001:4860:4860::8888 is the same address as 2001:4860:4860:0:0:0:0:8888. On IPv4, every device behind a home router usually shares one public address, and mobile networks often share one among many customers through carrier-grade NAT, in which case the address and its location belong to the carrier's gateway.
What do the location, ASN and reverse DNS fields tell you?
Location fields come from a database that maps blocks of addresses to places, so City, Region, Postal and the coordinates describe where the network block is registered or observed, often around the ISP's nearest hub. The latitude and longitude mark a point somewhere in that area and cannot pinpoint a home or office. Timezone follows the same estimated location, and any field the database lacks shows a dash.
Reverse DNS is the name the network owner has attached to the address: 8.8.8.8 returns dns.google and 1.1.1.1 returns one.one.one.one. Home connections often carry long names generated by the ISP, and many addresses have no name at all, which is normal. Anycast addresses such as those two are answered from data centers around the world, so a single city listed for them says little about where a request is served.
When should you use IP Lookup and when DNS Lookup?
IP Lookup starts from an address and tells you who runs it. DNS Lookup goes the other way, from a domain name to its records, so to find where a website is hosted, run an A or AAAA query there and paste the address it returns into this tool. Typical jobs here include checking that a VPN changes your visible location, finding your current public address for a firewall or database allowlist, and identifying the network behind an address in your server logs before you report abuse to its operator.
