WHOER is a browser-based IP lookup and privacy inspection service that helps people understand the information their internet connection and browser make visible online. Its home page brings IP details and browser-related observations together, giving users a practical starting point for reviewing a connection, checking a proxy configuration, or investigating differences between the environment they expected and the information a website can observe.

The service displays a public IP address alongside location and network information. Available fields include country, city, internet service provider, organization and autonomous system details. These observations help put an address in context: users can review which network is associated with a connection and compare the reported location with the region they intended to use. An IP-based location is an estimate associated with a network address, rather than a precise statement of a person’s physical location.

WHOER also presents browser and system information, including the browser, operating system, language, time zone and user-agent information. Looking at these details together can be useful when reviewing a browser profile or troubleshooting an unexpected result. For example, a user can compare the reported network region with the browser’s language and time settings, then investigate any differences in their own configuration. The site supplies observations for that review; it does not make configuration changes on the user’s behalf.

Privacy inspection features include DNS leak testing and WebRTC-related information. These checks address different ways that connection details may be exposed during browsing. A DNS test helps users examine the resolvers involved in requests, while WebRTC observations can help them review information made available through browser communication features. Checking these alongside the visible IP address provides a broader view than looking at a location field alone. Results depend on the connection, browser settings and the information available during the check.

The interface also includes proxy and anonymizer indicators, blacklist-related information and an anonymity assessment. These diagnostic signals can be considered alongside the underlying network and browser details when reviewing a connection.

In addition to its main diagnostic page, WHOER publishes explanatory articles and maintains resource pages covering residential proxies, antidetect browsers and related tools. These resources give readers additional background while they investigate connection settings or compare available services. Visitors can use the main page for a quick overview and explore the extended information when a more detailed review is needed.

WHOER is designed to make visible connection and browser information easier to inspect in one place. Visit: WHOER website to review the current tools, available fields and supporting resources.
