Detailed Features Introduction

Kung Fu W Detection

Supports detection of domain, IP, IP + port. This feature is quite special, and it's hard to explain in detail. You'll understand its specific purpose, just take a look at the image.

Dual Domain IP Detection

Sometimes when using magic internet access, there is usually a split between domestic and international access. The dual domain IP detection function can simultaneously monitor the IP addresses used by users when accessing domestic and overseas websites, helping to analyze traffic sources. As shown in the image below.

IPv6 Detection

When you visit TCP.mk, it will automatically detect IPv4 and IPv6. If IPv6 is supported, it will display the specific IP and location, otherwise it will show Not support.

IP Aggregation Query

TCP.mk supports viewing IP locations from multiple data sources for easy comparison and to avoid inaccuracies from a single source.

IP Batch Query

TCP.mk provides IP batch detection feature, supporting up to 50 IPs at once, and allows exporting the query results to a CSV table.

HTTP Detection

Through the HTTP detection feature, you can quickly check the website access status, as shown in the image below.

TCP Port Detection

This feature can check the connectivity of a specified IP and port, greatly facilitating new users in determining whether a port is reachable after opening it in the firewall.

Online Dig Command

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

API Calls

For developers, TCP.mk also provides API calls, currently only open for IP queries. For details, 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 features to meet the needs of different users. Feel free to visit and experience it: https://tcp.mk/
