THE EVERYDAY IP TOOLKIT
Your public IP, the records behind a name, and the numbers that shape a network.
The source address seen by this service. A router, VPN or proxy may sit between you and the internet.
A FEW GOOD TOOLS
Query public DNS records for a domain.
One resolver's answer, not a global propagation check. How to read DNS records ↗
Network, mask, broadcast and usable range. Calculated on your device. The starting /24 is illustrative, not your detected network; IPv6 connections use a documentation IPv4 example.
Supports /0 through /32, including point-to-point /31 networks.
Check IPv4 or IPv6 format, address scope and reverse DNS.
Address scope does not establish ownership or reachability. IPv4 vs IPv6 ↗
KNOW WHAT YOU ARE LOOKING AT
Public, not private. The IP above is the address this service sees—not necessarily the address assigned to your device.
One request, one path. A browser may use IPv6 while another connection uses IPv4. Neither result proves the other is unavailable.
DNS, with context. A record is not proof that a website is reachable. Check the response status and record type first.

Your provider may assign addresses dynamically. Switching Wi-Fi, mobile networks, VPN endpoints or IP protocols can change the address a service sees.
Not precisely. IP location databases are approximate and can describe a provider’s network rather than your device. ABOUTIP does not request GPS location. The time zone above comes from your browser.
No. The starting prefix is an example, not a measured network mask. Enter the IPv4 address and prefix you actually want to calculate. The calculation runs locally in your browser.
Yes. Use the CLI / API guide. The overall allowance is 40 requests per source IP in a rolling 60 seconds. Pages and API requests share it; DNS and reverse DNS have an additional shared lookup budget.
ABOUT THE TOOLKIT
ABOUTIP brings everyday IP and DNS questions into one small, free toolkit. No account or API key is required.
See your public source IP, query public DNS records, calculate an IPv4 subnet or inspect an IPv4 or IPv6 address. The field guides explain the results without pretending a lookup can prove more than it does.
We do not test your connection speed, locate your device precisely or determine who owns a device. The browser time zone comes from your browser, not an IP geolocation database. DNS answers come from one public resolver, not every network.
The current limit is 40 requests per source IP in a rolling 60 seconds, including pages and API requests. DNS and reverse-DNS calls also share a 30-lookup per-minute budget. Subnet calculations run on your device.
