Feature Details
Kung Fu W Detection
Supports detection of domain names, IPs, and IP + ports. This function is quite special and difficult to explain in detail; its specific purpose is self-evident. Please refer to the image below.

Dual-Domain IP Detection
Sometimes, if you use tools to access the internet, you generally perform domestic and overseas traffic splitting. The Dual-Domain IP Detection function can simultaneously monitor the IP addresses used by users when accessing domestic and overseas websites, helping to analyze access sources. As shown in the figure below.

IPv6 Detection
Visiting the TCP.mk homepage will automatically detect IPv4 and IPv6. If IPv6 is supported, the specific IP and location will be displayed; if not supported, it will display Not support.

IP Aggregation Query
TCP.mk supports viewing IP locations from multiple data sources, making it easy to compare and reference, while avoiding inaccuracies from a single data source.

IP Batch Query
TCP.mk provides an IP batch detection function, supporting up to 50 IPs at once, and allows exporting query results as CSV tables.

HTTP Detection
Through the HTTP detection function, you can quickly check website access status, as shown below.

TCP Port Detection
This function can detect the connectivity of a specified IP and port, greatly facilitating new users in determining if a port is reachable after allowing it through the firewall.

Online dig Command
Similar to the Linux dig command, it helps users obtain domain resolution-related information, such as IP addresses and MX records.

API Calls
For developers, TCP.mk also provides API calls. Currently, only IP queries are open. For details, please refer to the API documentation: https://tcp.mk/page/api
Conclusion
TCP.mk aims to help operations and development personnel improve efficiency. In the future, we will continue to expand more practical functions to meet the needs of different users. Welcome to visit and experience: https://tcp.mk/
