Check IP (checkip)
CheckIP brings together a range of free online utilities for users who want to examine their internet connection or troubleshoot common networking problems. The platform starts with a simple public IP checker and extends to tools that help investigate hosts, ports, proxies, connectivity, and blacklist status.
With IP Lookup, users can search for an IP address or domain to review available provider, ASN, and approximate location information. Port Scan helps test whether selected ports accept connections from the internet, while Check Host provides hosting and geolocation comparisons using multiple data sources. Ping testing helps measure response time, and the proxy checker can test supported proxy types.
CheckIP also offers blacklist lookup functionality for checking whether an IP appears on supported spam-related lists, which may help when investigating email delivery issues. An internet speed test provides another useful way to examine connection performance.
These tools serve different purposes and their results depend on the target, network configuration, and data sources available. Used appropriately, they can help users gather useful information before taking further troubleshooting steps. CheckIP aims to make these utilities accessible through a browser, with no account required for its core tools.
