About My IP
My IP is an independent website created to make IP address and network information easier to understand. It combines practical browser-based tools with plain-language explanations so that a visitor can check a connection, investigate a domain or learn a networking concept without installing software or creating an account.
The project is developed and maintained by João Edson Nunes Pereira, an information technology professional. My IP grew from a simple public IP checker into a collection of focused tools after testing the kinds of questions that commonly arise when configuring a network, diagnosing a connection or checking a domain.
Why My IP was created
An IP address is involved in almost every Internet connection, but the information surrounding it can be confusing. A result may show a nearby city instead of a visitor's exact location, an Internet provider may assign a different address later, and IPv4 and IPv6 results can behave differently on the same device. My IP was created to present these details clearly and to explain what each result can and cannot prove.
The goal is not only to display a number. Each tool is designed to give the result context: what the data means, where it comes from, why it may change and what a user can check next.
What you can do on My IP
The main page detects the public IP address used by the current Internet connection. Depending on network and provider support, the result may be IPv4 or IPv6. It can also display approximate IP-based location, Internet service provider, organization, ASN, time zone and basic browser or device information.
The IP Address Lookup tool can investigate another public IP address. DNS Lookup checks common DNS records for a domain or hostname. Reverse DNS checks whether an IP address has a PTR hostname. WHOIS Lookup uses RDAP data to display publicly available domain registration information. The Subnet Calculator helps calculate network address, broadcast address, usable host range, subnet mask and CIDR capacity.
My IP also publishes practical guides covering IPv4 and IPv6, public and private addresses, IP-based location, VPN behavior and the steps for finding an address on common operating systems and mobile devices.
How the results are produced
Different tools require different public data sources. Public IP detection and approximate network details can use My IP's server together with established IP information providers. DNS and reverse DNS queries may use public DNS resolution services. Domain registration results are requested through RDAP and sent to the registry service responsible for the domain extension.
The website validates user input before sending a supported query. Public IP lookup fields reject private or reserved addresses when those addresses cannot produce meaningful public geolocation results. Domain tools normalize common URL formats so that a visitor can enter a hostname without manually removing every URL component.
Accuracy and important limitations
IP geolocation is approximate. It is based on databases that map address ranges to providers and general service areas. It does not use a device's GPS location and should not be treated as an exact street address. Mobile networks, VPNs, corporate gateways, satellite connections and carrier-grade NAT can cause the displayed city or region to differ from the user's physical location.
DNS, RDAP and WHOIS-style information can also change. DNS updates may take time to propagate, registry fields may be redacted for privacy, and a domain's public data depends on the response supplied by its authoritative registry. For these reasons, My IP presents results as technical information rather than proof of identity, ownership or physical location.
Our editorial approach
Articles are written to support the tools and answer a specific networking question. When a procedure differs by operating system or device, the instructions are separated so the visitor can follow the relevant steps without sorting through unrelated information. Technical terms are explained in direct language, and important limitations are included close to the claims they affect.
Pages are reviewed when tools change, when a provider modifies its response or when operating-system instructions need to be updated. The site avoids presenting approximate network data as precise personal information. Corrections are incorporated into the relevant tool or guide when a reproducible problem is found.
Privacy and responsible use
Most My IP tools can be used without registration. Visitors should submit only public IP addresses, domains or hostnames that they are authorized to investigate. Passwords, authentication tokens and other confidential information should never be entered into lookup fields.
